Next Cache Components

Security checks for vulnerabilities and agentic risk

Overview

This is a benign Next.js caching reference skill, with only a minor privacy note around examples that read session or user cookies.

Review the cookie examples as documentation patterns: session and user identifiers can be sensitive, so only apply those snippets when your app actually needs them and avoid caching or propagating such values beyond the intended request/user scope.

A.I.G

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

Missing User Warnings

Low

Category: Not specified by scanner
Confidence: 82% confidence
Finding: This markdown file includes examples that access cookies() to read session and userId values, which are privacy-relevant user identifiers. Under the markdown-file warning criterion, the skill description should disclose behavior that may affect user data or privacy, but the surrounding text presents the pattern as a technical solution without any cautionary note.
Content: No source excerpt is available for this finding.
