Weak account passwords via str_shuffle generation
Published Dec 27, 2021 · Updated Aug 3, 2024
Weak randomness in WP Directory Kit Simple JWT Login before 3.3.0 allows remote attackers to create accounts with weak generated passwords. The registration path uses PHP's str_shuffle function to generate a password instead of a cryptographically secure random generator. The condition exists only when registration and optional random-password generation are enabled; successful password prediction compromises the created account.
