CodeRabbit Code Review
Security checks for vulnerabilities and agentic risk
Overview
This CodeRabbit review skill is mostly purpose-aligned, but it can trigger external code-diff uploads too broadly without clear user consent.
Install only if you are comfortable sending selected repository diffs to CodeRabbit. Before use, require the agent to show the exact files or diff range, exclude secrets and confidential paths, and get explicit approval before every external review run.
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 manifest description explicitly states that this skill should trigger autonomously whenever the agent 'thinks a review is needed,' which is broader than a narrowly scoped user-directed action. In practice, this can cause unprompted invocation of an external review tool that transmits code diffs to a third-party API, increasing the chance of unnecessary data exposure and unintended execution flow.
