Threats affecting pkg:pypi/rembg

Rembg versions prior to 2.0.82 have an unauthenticated vulnerability in the /api/remove endpoint that allows attackers to inject malicious SAM models via the extras.sam_model parameter. This enables path traversal and placement of crafted ONNX models that read arbitrary local files and encode their contents into returned PNG images. The flaw allows disclosure of any file accessible by the rembg process, including sensitive files like /etc/passwd. The issue is fixed in version 2.0.82.

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.
