[Security Alert] Your plugin astrbot_plugin_knowledge_base has been delisted

  ## AstrBot Plugin Security Alert

  Hello @lxfight,

  Your plugin **astrbot_plugin_knowledge_base** (version v0.5.7) has been automatically delisted from the AstrBot Trusted Marketplace due to a potential security issue found during our automated audit.

  **Reason:**
  ```
  The plugin allows adding a file from a user-provided 'path_or_url'. This functionality is susceptible to Path Traversal vulnerabilities, potentially allowing users to read arbitrary files from the server's file system, and Server-Side Request Forgery (SSRF) by providing internal network URLs.
  ```

  Please review the findings and push an updated version. The new version will be automatically re-audited.

  Thank you,
  The AstrBot Team
