Security audit
chrome-extension-research
Security checks for vulnerabilities and agentic risk
Overview
This skill is a disclosed Chrome extension research helper that sends user-directed queries to Crawlora's API and does not show hidden persistence, privilege escalation, or unrelated data access.
Install only if you are comfortable sending Chrome extension search terms, extension IDs, and related research queries to Crawlora along with your Crawlora API key. Keep the key in the environment, avoid placing secrets or private local file contents in request bodies, and treat store metadata as research evidence rather than proof that an extension is safe.
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
- Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
- Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
- MCP Least PrivilegeUnderdeclared Capability, Wildcard Permission, Missing Permission Declaration
- Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
- Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Sudo/Root Execution

- Privilege Escalation

# Keep the API key out of the curl process command line. A private temporary # config supplies the header and is removed automatically on exit. curl_config="$(mktemp "${TMPDIR:-/tmp}/crawlora-curl.XXXXXX")" chmod 600 "$curl_config" trap 'rm -f "$curl_config"' EXIT printf 'header = "x-api-key: %s"\n' "$CRAWLORA_API_KEY" >"$curl_config" auth=(--config "$curl_config")- Confidence
- 80% confidence
- Finding
- Commands invoke sudo or root privileges. Verify this elevated access is necessary and justified.

Natural-Language Policy Violations
Low
- Confidence
- 89% confidence
- Finding
- Several endpoint descriptions specify defaults including `lang=en`, presenting English as the automatic locale choice. This is a natural-language locale policy concern because the document does not indicate user opt-in, alternatives, or a justified region-specific constraint.
