Refuted findings 3
Candidates the review stage examined and rejected, kept for transparency.
Data exfiltration
criticalRefutedlow confidencegenerate_screenshots reads any local file path supplied by the agent (no image-type restriction, falls back to application/octet-stream) and uploads it to the remote StoreShots API, so a prompt-injected path could send arbitrary local files (up to 10 MB) off-host.
buf: await fs.readFile(p), type: MIME[path.extname(p).toLowerCase()] || 'application/octet-stream'
Why it was refuted
Reading a local file path and uploading it to the StoreShots API is the declared core function of generate_screenshots. The tool description openly says it takes local file paths, and the upload goes only to the wrapped service. The missing image-type check is a hardening gap, not undeclared or concealed behaviour.
Data exfiltration
criticalRefutedlow confidencegenerate_screenshots reads any local file path supplied by the agent (not restricted to image types) and uploads it to the remote StoreShots API, so a prompt-injected agent could send arbitrary local files off-host; the file read is part of the declared function but its reach is unrestricted.
return { buf: await fs.readFile(p)Why it was refuted
This is the same file read as the first finding. It is the declared core capability of uploading user-supplied local screenshots to the StoreShots API, and the finding itself concedes the read is part of the declared function.
Destructive action
criticalRefutedlow confidencedownload() writes API-supplied bytes into an agent-chosen directory (output_dir/download_to), overwriting existing files with matching names. File names are sanitised by safeRel, so the risk is limited to overwriting files in an arbitrary directory.
await fs.writeFile(dest, buf);
Why it was refuted
Writing downloaded outputs to a caller-chosen directory is the declared core function of get_output and download_to. The overwrite behaviour is stated in the tool descriptions, and safeRel sanitises file names against traversal. The detector's contradiction with the list_devices read-only claim is a line-attribution mismatch.
