Vulnerability Type: Unbounded access to potentially sensitive contextual records
Risk Level: MediumVulnerable Code Snippet:
markdown 1. **Profile Analysis**: Consults `PROFILE_FILE` for preferred actors, genres, and themes. 2. **Context Check**: May check recent logs or mood to suggest a matching "vibe".Technical Analysis
The instruction permits the agent to inspect unspecified “recent logs” while generating movie recommendations. It does not identify an approved log source, define a path boundary, require user consent, or limit collected information to movie-related data.
Consequently, an agent with filesystem, conversation-history, or application-log access could interpret this instruction broadly and read records outside
MOVIES_ROOTorPROFILE_FILE. Such records may contain private conversations, activity history, operational metadata, or other information unrelated to movie recommendations. This violates least-privilege and data-minimization principles.No instruction to transmit the accessed information to an external party was identified, and the actual accessible scope remains dependent on the permissions granted to the hosting agent.
Attack Path
- A user invokes the skill and requests a movie recommendation.
- The recommendation workflow reaches the optional context-check step.
- The agent interprets “recent logs” as authorization to inspect available chat, application, agent, or filesystem logs.
- The agent reads records unrelated to the movie-management task.
- Sensitive details from those records may influence or appear in the generated recommendation, exposing information without explicit user approval.
Impact Assessment
The issue may permit unauthorized read access to any recent logs already reachable through the agent's granted tools and operating-system permissions. Potentially exposed info ...[truncated 413 chars]

Remediation Suggestions
- Remove the generic authorization to inspect “recent logs.”
- Restrict contextual analysis to explicitly named, movie-related files under
MOVIES_ROOT, such asPROFILE_FILE. - Require informed user consent before reading any additional context source.
- Explicitly prohibit access to general chat histories, system logs, agent logs, application logs, and files outside the configured movie directory.
- Apply path canonicalization and verify that approved files remain within
MOVIES_ROOTbefore reading them. - Minimize retained data and avoid copying sensitive contextual details into recommendations or persistent profile files.
- Replace the affected instruction with a bounded version, for example:
markdown 2. **Context Check**: With explicit user consent, consult only the configured `PROFILE_FILE` or a user-selected movie journal located under `MOVIES_ROOT`. Do not access chat histories, system logs, agent logs, application logs, or unrelated files.
