Security checks for vulnerabilities and agentic risk

Overview

The skill matches its recruiting purpose, but it needs review because it sends recruiting searches and candidate handles to Apify and its REST examples put the Apify token in URL query strings.

Review before installing. Use this only when you intend to send recruiting search criteria and candidate handles to Apify. Prefer an Apify MCP or API method that keeps the token in an Authorization header, use a least-privilege token, set explicit maxItems limits, and avoid scraping or storing more candidate data than needed.

Vulnerability Patterns
  • Insecure Skill Coding PracticesFinds exploitable flaws such as hardcoded secrets or command injection
  • 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

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
97% confidence
Finding

The trigger description enumerates many loosely related recruiting intents and social-search scenarios without clear activation constraints. Overbroad triggers can cause the skill to activate on ambiguous user requests and initiate external social-media scraping or candidate profiling when the user did not clearly intend that behavior.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The documentation instructs sending search terms and usernames to Apify actors, but it does not require an explicit disclosure or consent step before transmitting potentially sensitive search criteria or personal identifiers to a third party. In a recruiting context, this can expose hiring intentions, targeted individuals, or internal sourcing criteria to an external service without informed user approval.

External Transmission

Medium
Category
Data Exfiltration
Confidence
96% confidence
Finding

This command sends search terms directly to an external Apify endpoint, creating a clear outbound data flow to a third party. In this skill's recruiting context, the transmitted queries can reveal sensitive business intent such as active hiring plans, target roles, or sourcing strategy, and the documentation does not require prior user consent or data minimization.

  -d '{"searchTerms": ["growth marketer", "VP Marketing", "marketing open to work", "content marketing jobs"], "maxItems": 300}'

External Transmission

Medium
Category
Data Exfiltration
Confidence
50% confidence
Finding

Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.

External Transmission

Medium
Category
Data Exfiltration
Confidence
96% confidence
Finding

This API example transmits a list of usernames to a third-party service for profile enrichment. Even though the usernames are public identifiers, sending targeted candidate lists to an external processor can disclose recruitment targets and create privacy/compliance concerns, especially when combined with profile scoring and open-to-work inference.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
98% confidence
Finding

The example input sets "tweetLanguage": "en", which enforces an English-only search scope. The document does not present this as optional or offer the user a language choice, creating a locale/language policy concern.
