Security audit
social-media-api
Security checks for vulnerabilities and agentic risk
Overview
This is a disclosed API wrapper for public social and web data, with the contact-data endpoints visible for explanation but blocked from calls.
Before installing, understand that this can spend ScraperSocial credits and retrieve large amounts of public social/web data. Use it only for data you are authorized to collect, and note that contact-detail endpoints are intentionally not callable from this skill.
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

Description-Behavior Mismatch
High
- Category
- Not specified by scanner
- Confidence
- 99% confidence
- Finding
The skill metadata claims that personal-contact endpoints are excluded, but the endpoint catalog includes entries marked personalData=true, such as Google Maps contacts and LinkedIn contact-related capabilities. This mismatch can mislead downstream users, reviewers, or policy gates into enabling data-collection functionality they believed was absent, creating privacy, compliance, and trust risks.

Description-Behavior Mismatch
High
- Category
- Not specified by scanner
- Confidence
- 100% confidence
- Finding
The LinkedIn profile-contact endpoint explicitly exposes contact-oriented data while the skill description states that personal-contact endpoints are excluded. In a social-media scraping skill, that contradiction is especially dangerous because it increases the chance that operators will unintentionally collect personal data under false assumptions about the tool's scope.

Natural-Language Policy Violations
Low
- Category
- Not specified by scanner
- Confidence
- 83% confidence
- Finding
The file includes Naver-specific endpoints and summaries, which implicitly target a Korean-language/locale ecosystem, but the manifest-style data provides no indication that this locale scope is optional or user-selected. Under the policy, forcing or assuming a specific language/locale without opt-in can be a natural-language policy concern when not clearly documented as region-specific.
