Doc Text:	A flaw was found in Seahub. This vulnerability occurs because the batch share link creation feature generates passwords using a cryptographically weak random number generator. An authenticated remote attacker can request multiple passwords to determine the generator's internal state, enabling them to predict share link passwords generated for other users and gain unauthorized access to shared files.

Description OSIDB Bzimport 2026-11-10 13:01:06 UTC

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.
