Security checks for vulnerabilities and agentic risk
Overview
The skill coherently documents Workday data reads through your signed-in browser and clearly discloses its persistent browser pairing.
Use this only with authorization to access the relevant Workday information. Review the extension's requested domains and capabilities, verify its release checksum, and revoke pairing when no longer needed. Keep session tokens and sensitive HR output out of shared logs. Access can include employee information your account can view; the external CLI and extension binaries were not audited here.
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
