Security checks for vulnerabilities and agentic risk

Overview

ClawScan marks this skill suspicious because a scanner found it may publish runtime session links in pull request text without checking whether sharing is authorized; the review is incomplete because a referenced local path was missing.

Before installing, consider whether the skill could publish a runtime session link to a pull request and who can see it. The scanner says the link's actual exposure depends on the session service's access controls. Treat the review as incomplete because a referenced local path was missing; the results do not establish that the artifact is safe.

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

Finding

The skill instructs the agent to publish a runtime session URL whenever one is present, without checking whether the user authorized sharing it or whether the PR audience may access session information. A public or broadly visible PR could expose a private session identifier or, if the link grants access, sensitive session contents; the actual exposure depends on the session service's access controls. Requiring an exact runtime-provided URL reduces fabrication risk but does not establish permission to publish it.
