Parsera

Security checks for vulnerabilities and agentic risk

Overview

The skill is mostly coherent for Parsera use, but its setup instructions include unverified remote installers that can execute code on the user's machine.

Install only if you are comfortable with the OOMOL oo CLI and Parsera account connection model. Do not run the documented remote installer pipeline blindly; prefer an official package or a downloaded installer that you can verify before execution, and approve any first-time setup steps explicitly.

Vulnerability Patterns

Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
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
Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

External Script Fetching

High

Category: Supply Chain
Confidence: 97% confidence
Finding: The skill includes a one-line remote installation command that downloads a script over the network and pipes it directly into a shell. If the install endpoint, CDN, TLS trust chain, or upstream release process is compromised, an agent or user following this instruction could execute attacker-controlled code immediately on the host.

Vague Triggers

Medium

Category: Not specified by scanner
Confidence: 96% confidence
Finding: This markdown file defines when the skill should be used, and the trigger language is extremely broad. It does not provide exclusions or negative examples, so agents may invoke the skill for loosely related mentions of Parsera rather than clearly scoped tasks.
Content: No source excerpt is available for this finding.
