CVE-2026-24486
Good to know:
Date: January 26, 2026
Python-Multipart is a streaming multipart parser for Python. Prior to version 0.0.22, a Path Traversal vulnerability exists when using non-default configuration options "UPLOAD_DIR" and "UPLOAD_KEEP_FILENAME=True". An attacker can write uploaded files to arbitrary locations on the filesystem by crafting a malicious filename. Users should upgrade to version 0.0.22 to receive a patch or, as a workaround, avoid using "UPLOAD_KEEP_FILENAME=True" in project configurations.
