Detailsinfo

A vulnerability was found in AstrBot 3.5.22. It has been declared as problematic. This vulnerability affects the function _encode_image_bs64 of the file entities.py. The manipulation with an unknown input leads to a path traversal vulnerability. The CWE definition for the vulnerability is CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. As an impact it is known to affect confidentiality. CVE summarizes:

AstrBot Project v3.5.22 has an arbitrary file read vulnerability in function _encode_image_bs64. Since the _encode_image_bs64 function defined in entities.py opens the image specified by the user in the request body and returns the image content as a base64-encoded string without checking the legitimacy of the image path, attackers can construct a series of malicious URLs to read any specified file, resulting in sensitive data leakage.

The advisory is shared for download at github.com. This vulnerability was named CVE-2025-57697 since 08/17/2025. The exploitation appears to be easy. There are known technical details, but no exploit is available. The MITRE ATT&CK project declares the attack technique as T1006.
