CI Tools Monthly Digest

Security checks for vulnerabilities and agentic risk

Overview

ClawScan rates this skill benign because the reported behavior appears aligned with its purpose, while noting some policy and tool-scope issues and incomplete evidence.

The verdict is benign with medium confidence, not a guarantee of safety. Before installing, consider whether English-only output and the detected network and shell capabilities fit your needs. Evidence is incomplete: skillspector could not resolve a local path-like reference, even though it scanned all listed components, and runtime permissions are unknown.

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
  • Output HandlingUnvalidated Output Injection, Cross-Context Output, Unbounded Output
  • Behavioral ASTexec() Call, eval() Call, Dynamic Import
  • MCP Least PrivilegeUnderdeclared Capability, Wildcard Permission, Missing Permission Declaration
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
Findings (4)

The automation requires an English digest without offering a language choice or documenting a justification.

Medium

Output Handling
Confidence
96% confidence
Finding

Both the job description and agent payload explicitly require the digest to be in English. The file provides no user opt-in, language choice, or documented justification for this language constraint.

Content

No source excerpt is available for this finding.

Skill declares no tool scope ('permissions' or 'allowed-tools') but code capabilities were detected: network, shell.

Medium

MCP Least Privilege
Confidence
70% confidence
Finding

Without declared permissions the skill's intent is opaque and cannot be validated.

Content

No source excerpt is available for this finding.

The skill mandates English output without user opt-in or a documented justification.

Medium
Category
Output Handling
Confidence
99% confidence
Finding

The instruction requires the entire digest, including headings, to be written in English. Although the description advertises English output, the skill neither offers a language choice nor explains why this language restriction is necessary.

subprocess module call

Confidence
70% confidence
Finding

subprocess module calls execute external commands. Without careful input validation, this enables command injection.
