Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-125: Out-of-bounds Read, where the product reads data past the end, or before the beginning, of the intended buffer. In AstrBot, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

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.
