Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed Feishu document-management helper, but users should be careful with document edits, collaborator permissions, and the unpinned GitHub install instructions.

Install from a reviewed version when possible, or pin and inspect the GitHub repository before placing it in the active skills directory. Use least-privilege Feishu credentials and confirm any document deletion, overwrite, or collaborator permission change before allowing the agent to act.

Vulnerability Patterns

Insecure DependenciesIntroduces malicious components through unsafe dependency sources
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

``` 2. Publish signed, versioned releases and instruct users to verify the release signature before installation. 3. Provide a cryptographic checksum for each reviewed release archive and require checksum validation. 4. Review all skill instructions, scripts, manifests, and dependencies before placing the repository in an active skills directory. 5. Download and inspect the repository in a staging location first, then copy only reviewed files into the skills directory. 6. Apply least-privilege controls to the OpenClaw process and Feishu credentials so a compromised skill cannot access unrelated local resources or documents. 7. Document the exact audited version and establish a controlled update process that requires security review before changing the pinned revision. ]]>

Missing User Warnings

Medium

Category: Not specified by scanner
Confidence: 91% confidence
Finding: The skill advertises document creation, writing, deletion, and collaborator/permission management but does not clearly warn users that these actions can modify or expose documents. In an agent setting, missing safety guidance increases the chance of accidental destructive edits or unintended permission grants, especially when the model acts on ambiguous user requests.
Content: No source excerpt is available for this finding.

Natural-Language Policy Violations

Low

Category: Not specified by scanner
Confidence: 78% confidence
Finding: The file consistently presents the skill in bilingual English/Chinese form and brands it as a Chinese-language Feishu tool, but it does not state whether language output is optional or user-selectable. Under SQP-3, forced language or locale behavior without opt-in can be a policy concern when no choice is offered.
