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": "I validated one grounded vulnerability in the QQ Bot extension: structured media payloads accept attacker-controlled local filesystem paths, and the reply dispatcher reads those files and forwards their contents to QQ Bot upload APIs without constraining the path to a QQ Bot-owned media directory. The path helper used here normalizes and optionally remaps paths, but in this checkout it does not enforce containment under `~/.openclaw/media/qqbot` or another allowlisted root.",
  "reports": [
    {
      "title": "Structured QQ Bot media payloads allow arbitrary local file disclosure via attacker-controlled payload.path",
      "severity": "HIGH",
      "summary": "`QQBOT_PAYLOAD` media messages can specify `source: \"file\"` and an arbitrary `path`. In `reply-dispatcher.ts`, image, video, and file handlers normalize and resolve that path, then read the referenced local file and upload its contents to QQ Bot APIs. The resolver in `platform.ts` does not restrict paths to QQ Bot-owned media storage; if the file exists, it returns the normalized path unchanged. As a result, an attacker who can cause a structured media payload to be processed can exfiltrate readable local files from the host.",
      "rootCauseAnalysis": "The root cause is missing path confinement for structured local media payloads. `parseQQBotPayload()` accepts any string `path` for media payloads. `handleImagePayload()`, `handleVideoPayload()`, and `handleFilePayload()` call `resolveQQBotLocalMediaPath(normalizePath(payload.path))`, but `resolveQQBotLocalMediaPath()` only normalizes the path and tries best-effort remapping for missing files. It explicitly returns the normalized path unchanged when `fs.existsSync(normalized)` is true, and it never checks that the canonicalized path resides under `getQQBotMediaDir()` or another QQ Bot-controlled root. The handlers then call `fileExistsAsync()`, `checkFileSize()`, and `readFileAsync()` on that path, base64-encode the content, and pass it into `sendC2C*`/`sendGroup*` upload flows, which place the bytes into `file_data` for QQ Bot `/files` API requests.",
      "impact": "Any readable local file within the upload size limit can be disclosed to the QQ Bot conversation target. This can expose secrets such as configuration files, tokens, SSH keys, application data, or other sensitive host files, subject to process read permissions and the 20 MB upload limit.",
      "attackPath": "An attacker supplies or induces a reply containing `QQBOT_PAYLOAD:` JSON with `type: \"media\"`, `source: \"file\"`, and a chosen local `path` such as `/etc/passwd` or another readable file. The dispatcher parses the payload, treats the path as local, reads the file from disk, converts it to base64, and sends it through `uploadC2CMedia()` or `uploadGroupMedia()` to QQ Bot, disclosing the file contents in-band to the attacker-controlled chat target.",
