AI Security Review
scanned 26d ago · by lpm-firewall-aiStatic inspection found a concrete unauthenticated network exposure when the optional synchronization token is absent. This is a critical vulnerability, but the source does not establish malicious package intent or install-time abuse.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
A user runs the Osborn application and the API server starts without OSBORN_SYNC_TOKEN.
Impact
A reachable unauthenticated client could obtain Claude session and skill data or cause archive-based changes to the Claude projects area.
Mechanism
The server binds to 0.0.0.0, exports Claude projects and skills, and accepts archive imports; token validation occurs only conditionally when the environment variable is present.
AI rationale
Static inspection found a concrete unauthenticated network exposure when the optional synchronization token is absent. This is a critical vulnerability, but the source does not establish malicious package intent or install-time abuse.

Network endpoints3
0.0.0.0/sessions/export/sessions/import
Decision evidence
public snapshotAI called this Suspicious at 94.0% confidence as Critical Vulnerability with low false-positive risk.
Evidence for warning
- The package exposes a network API with permissive cross-origin access and binds it to all interfaces by default.
- The API can export Claude project and skill data, with authorization enforced only when an optional environment token is set.
- The API accepts session archives for extraction into the Claude projects directory under the same optional-token gate.
- The package has no install lifecycle hook; its entrypoints are user-invoked command binaries.
Evidence against
- No install-time execution or self-dependency chain was found in package metadata.
- The observed behavior is an exposed application API, not evidence of covert malware or a package-controlled exfiltration recipient.
