Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
A vulnerability was determined in AstrBotDevs AstrBot 4.23.6. Affected by this issue is the function _normalize_rw_path of the file astrbot/core/tools/computer_tools/fs.py. This manipulation causes incorrect authorization. It is possible to initiate the attack remotely. The exploit has been publicly disclosed and may be utilized. The vendor was contacted early about this disclosure but did not respond in any way.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

A path authorization vulnerability exists in the _normalize_rw_path function in astrbot/core/tools/computer_tools/fs.py. The function fails to properly validate or authorize file system paths, likely allowing path traversal or unauthorized file access. This is a remote authorization bypass in a file handling function.

MitigationFix the _normalize_rw_path function to properly canonicalize paths and enforce authorization checks before allowing file operations. Validate all paths against intended access controls and prevent traversal beyond permitted directories.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Verify AstrBot installation and version
    Check if AstrBot version 4.23.6 is installed. Run: pip show astrbot or check package metadata to get the installed version number.
    Affected if The installed version is exactly 4.23.6 (the affected version)
  2. Locate the vulnerable file
    Find the file astrbot/core/tools/computer_tools/fs.py in the AstrBot installation directory. Common paths: site-packages/astrbot/core/tools/computer_tools/fs.py or the project source directory.
    Affected if The file exists in the AstrBot installation
  3. Inspect the _normalize_rw_path function
    Open fs.py and locate the _normalize_rw_path function. Examine whether it uses os.path.realpath() or equivalent canonical path checks to ensure resolved paths stay within allowed directories.
    Affected if The function exists but lacks proper path validation (no realpath() check or directory boundary enforcement)
  4. Check if file operations are enabled
    Determine whether the file read/write tool/feature is enabled or accessible in AstrBot configuration. This may be in config files or tool enablement settings.
    Affected if File read/write operations via computer_tools are enabled and accessible to users

You are affected if AstrBot 4.23.6 is installed, the vulnerable fs.py file exists, and the _normalize_rw_path function lacks proper path validation to prevent path traversal attacks.
