Description
Rembg is a tool to remove images background. Prior to 2.0.75, a path traversal vulnerability in the rembg HTTP server allows unauthenticated remote attackers to read arbitrary files from the server's filesystem. By sending a crafted request with a malicious model_path parameter, an attacker can force the server to attempt loading any file as an ONNX model, revealing file existence, permissions, and potentially file contents through error messages. This vulnerability is fixed in 2.0.75.
Analysis
Unauthenticated remote attackers can exploit a path traversal vulnerability in rembg's HTTP server (versions prior to 2.0.75) by sending a crafted request with a malicious model_path parameter to read arbitrary files from the server filesystem. The vulnerability allows attackers to enumerate file existence and permissions, and potentially extract file contents through verbose error messages when the server attempts to load arbitrary paths as ONNX models. …
