Novel Video & Audiobook Multi-Voice Voiceover

Security checks for vulnerabilities and agentic risk

Overview

ClawScan’s verdict is benign with medium confidence: the scanners report no AIG findings, while Skillspector notes a mismatch between the advertised voiceover workflow and the code it assessed, plus some capability and resource-use concerns.

The verdict is benign, not a guarantee of safety. Before installing, consider whether the reported mismatch with the advertised features and the unbounded API timeout matter for your use. Scanner evidence is incomplete because Skillspector could not resolve some local references.

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
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
  • Behavioral ASTexec() Call, eval() Call, Dynamic Import
  • MCP Least PrivilegeUnderdeclared Capability, Wildcard Permission, Missing Permission Declaration

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
97% confidence
Finding

The code implements a relevant low-level API client, but not the materially richer end-to-end workflow described. Each generation request accepts one actor or reference-audio URL, and output saving handles one returned result rather than assembling the advertised multi-role deliverables. Network access to Miragea, reading explicitly selected files, and writing requested output files are consistent supporting operations; there is no evident unrelated data collection. This assessment is limited to the supplied code chunk.

Content

No source excerpt is available for this finding.

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

Medium
Category
MCP Least Privilege
Confidence
70% confidence
Finding

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

No source excerpt is available for this finding.

Unbounded Resource Access

Medium
Category
Excessive Agency
Confidence
75% confidence
Finding

Skill allows unbounded resource consumption (API calls, storage, compute). Without rate limits or quotas, a compromised or misbehaving agent can cause denial-of-service or cost overruns.

subprocess module call

Medium
Category
Dangerous Code Execution
Confidence
70% confidence
Finding

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

Content

python
cmd += [flag, str(p[k])]
    for t in p.get("tags", []):
        cmd += ["--tag=" + t]
    r = subprocess.run(cmd, capture_output=True, text=True)
    if r.returncode != 0 or not os.path.exists(out_path):
        sys.stderr.write(r.stdout + r.stderr)
        raise ScriptError("generate failed for: %s... Re-run the same command to resume; the same idempotency key "

Dynamic attribute access via getattr()

Low
Category
Dangerous Code Execution
Confidence
50% confidence
Finding

Dynamic getattr() with a non-literal attribute name can access arbitrary object attributes, potentially bypassing access controls.
