Security audit
musescore-fpx
Security checks for vulnerabilities and agentic risk
Overview
This skill is a clearly scoped MuseScore helper that uses a browser bridge to fetch public/search metadata and does not show hidden or destructive behavior.
Install only if you are comfortable granting ContextMint Bridge access to musescore.com and reusing your browser session for those requests. Keep the extension's site access limited to musescore.com, verify the extension release or build it yourself, and do not use the workflow to automate purchases or bypass MuseScore entitlements.
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
- Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
- Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
- Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
- Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
- Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
