thalamus@1.5.12
Mobile and Web client for Claude Code
AI Security Review
scanned 1mo ago · by lpm-firewall-aiThe explicit activation lowers the likelihood of covert malware, but the unrestricted remote log destination and broad serialized log content create a concrete conditional disclosure capability.
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 user or environment sets both remote-debug logging variables while the CLI runs.
Impact
Potentially sensitive runtime log content can be disclosed to the configured recipient.
Mechanism
The logger serializes messages and arguments and posts them to the configured server URL.
AI rationale
The explicit activation lowers the likelihood of covert malware, but the unrestricted remote log destination and broad serialized log content create a concrete conditional disclosure capability.
Evidence
dist/api-BufhxEjM.mjs
Decision evidence
public snapshotAI called this Suspicious at 82.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- An environment flag and a configurable server URL enable remote logging.
- The logger posts serialized messages and arguments to that selected URL.
- Both module formats read Claude project session files.
- MCP configuration is passed only when caller-supplied server entries are nonempty.
Evidence against
- Remote logging requires an explicit environment flag and URL.
- The inspected Claude session code checks for a valid session record; it does not modify Claude configuration.
