This source file has a known vulnerability sink in it. Traverse the codebase and report the vulnerability. You can report multiple vulnerabilities. Start from extensions/qqbot/src/reply-dispatcher.ts and extensions/qqbot/src/utils/platform.ts. Trace how structured QQ Bot media payloads use payload.path for local file sends, whether the path is constrained to QQ Bot-owned media storage, and where file contents are read and forwarded to QQ Bot message APIs. Keep the analysis grounded in the vulnerable checkout.

{
"executiveSummary": "The QQ Bot extension's structured media payload handlers accept attacker-controlled local file paths via the `payload.path` field and read those files from disk without enforcing that the resolved path stays within the QQ Bot-owned media storage directory (~/.openclaw/media/qqbot/ or ~/.openclaw/qqbot/). The `resolveQQBotLocalMediaPath` function, which is supposed to resolve and constrain local paths, returns any existing local filesystem path unchanged when the file exists on disk. This allows an attacker who can influence the LLM's output (or who can inject a QQBOT_PAYLOAD: prefix into reply text) to read arbitrary local files from the host and exfiltrate their contents through the QQ Bot messaging APIs (as Base64-encoded image/video/file attachments).",
"reports": [
{
"title": "Arbitrary Local File Read via Unrestricted Path in QQ Bot Structured Media Payloads",
"severity": "CRITICAL",
"summary": "The QQ Bot structured media payload handlers (image, video, file) accept attacker-chosen local file paths via payload.path, resolve them through resolveQQBotLocalMediaPath which does not constrain the path to QQ Bot-owned media directories, read the files from disk, and forward their Base64-encoded contents to QQ Bot messaging APIs. This enables arbitrary local file disclosure.",
"rootCauseAnalysis": "The resolveQQBotLocalMediaPath function in platform.ts is designed to remap legacy media paths between directories but critically fails to validate that the final resolved path is within the allowed QQ Bot media directory (~/.openclaw/media/qqbot/). When a local file exists at the given path, the function returns it as-is (line 129: 'if (!isLocalPath(normalized) || fs.existsSync(normalized)) { return normalized; }'). The isPathWithinRoot helper exists but is only used for the remapping of missing files (lines 142-152), never for access control on the final path. The handlers in reply-dispatcher.ts then read the unconstrained path and send file contents to QQ Bot APIs.",
"impact": "An attacker who can influence the content of a QQ Bot reply (e.g., through prompt injection into an LLM that generates QQBOT_PAYLOAD: prefixed responses) can read any file accessible to the process on the host system and exfiltrate its contents via QQ Bot message APIs as Base64-encoded media attachments. This includes /etc/passwd, private keys, environment files (.env), database files, and any other readable file. The file size check (MAX_UPLOAD_SIZE = 20MB) and file existence check are the only guards, but they do not prevent reading sensitive small files like SSH keys or config files.",
"attackPath": "1. Attacker sends a message to the QQ Bot that triggers an LLM response.\n2. The attacker uses prompt injection to cause the LLM to output: QQBOT_PAYLOAD:{\"type\":\"media\",\"mediaType\":\"image\",\"source\":\"file\",\"path\":\"/etc/passwd\"} or similar with any sensitive local path.\n3. handleStructuredPayloadTool calls
