python3-multipart: Python-Multipart is a streaming multipart parser for Python
CVE-2026-24486 is fixed in 3 products on 1 platform, first by python3-multipart 0.0.5-2ubuntu0.1~esm1, released January 26, 2026. It is not reported as exploited. Patch Radar priority: High.
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.
