Security audit

Remix V2 Meta Sessions

Security checks for vulnerabilities and agentic risk

Overview

This is a documentation-only Remix guidance skill with security-focused examples that match its stated purpose.

Before installing, treat the Remix code snippets as templates and adjust details such as `lang`, cookie names, session duration, and SameSite policy for your application. The skill is documentation-only and its security-sensitive examples are directly related to Remix auth, sessions, and CSRF hardening.

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
Vulnerability Patterns
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep

Finding

The example sets <html lang="en">, which imposes a specific language/locale in natural-language guidance. The file does not indicate this is merely illustrative, offer a user-selectable alternative, or justify an English-only constraint for a region-specific tool.
