Telegram bridge for DeepSeek Harness: text, voice, photos and project-per-topic sessions without opening the desktop app
AI Security Review
scanned 8d ago · by lpm-firewall-aiThe probe serves a normal provider health-check purpose, but its independent URL override can receive a saved profile key automatically. This conditional credential exposure warrants a warning, not a block.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source
Trigger
A bridge turn returns an error that matches its fallback trigger, causing the model probe to run.
Impact
If the URL override points somewhere that should not receive the profile key, that credential may be exposed automatically during the probe.
Mechanism
The probe uses UNOROUTER_BASE_URL when set, but falls back to the active profile’s key name unless UNOROUTER_API_KEY is set, then sends the key as a bearer credential to that URL.
AI rationale
The probe serves a normal provider health-check purpose, but its independent URL override can receive a saved profile key automatically. This conditional credential exposure warrants a warning, not a block.
Evidence
bridge.mjsmodel-probe.mjs
Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The probe loads a provider key from its configured environment variable or the DSH credentials file, and reads the provider URL and key name from the active profile.
- The UNOROUTER_BASE_URL environment variable can replace the profile URL while the profile key remains selected when UNOROUTER_API_KEY is unset; the inspected code shows no destination allowlist.
- The probe sends that key as a bearer credential in a one-token request to the selected URL.
- The bridge calls the probe after a matching turn error, so saved credentials may be sent automatically without a separate prompt at the time of transfer.
- The control handler accepts a command and callbacks from its caller, including send and reply.
- The panel step formatter reads tool event fields and selects command, description, file, path, pattern, query, or URL text.
- The settings callback parser checks the settings prefix and splits the callback into row and value fields.
Evidence against
- The probe’s request body contains a model name and a short health-check message; the inspected source does not show unrelated data being collected or sent.
