V2EX

Security checks for vulnerabilities and agentic risk

Overview

The skill is mostly coherent for managing a V2EX account, but it needs review because its setup instructions include running a remote installer directly in the user's shell.

Review before installing. Use this only if you trust OOMOL and are comfortable connecting a V2EX account through its connector. Avoid blindly running the provided remote installer commands; prefer a verified official install path. Confirm any boost, sticky, token creation, or deletion action before it runs.

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

Credential Access

High

Privilege Escalation
Confidence
70% confidence
Finding

Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.

External Script Fetching

High
Category
Supply Chain
Confidence
97% confidence
Finding

The skill recommends installing software via curl ... | bash, which executes a remote script directly without integrity verification or review. If the install endpoint, transport path, or hosting account is compromised, arbitrary code could run on the user's system under their shell context.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
91% confidence
Finding

The description uses an extremely broad activation condition: any task involving V2EX should invoke this skill. While the domain is specific, the trigger scope is still ambiguous because it does not define boundaries, exclusions, or examples of when not to use the skill, increasing the chance of unintended invocation whenever V2EX is merely mentioned.
