Description

Seahub through 14.0.10 contains a weak randomness vulnerability in MultiShareLinksBatch.post() that generates batch share link passwords using Python's non-cryptographic random.choices(). Authenticated users permitted to create share links can request many generated passwords via the multi-share-links batch endpoint, recover the Mersenne Twister state, and predict other users' share link passwords.
