CVE-2026-112768

Full vulnerability record from the local CVENow database.

Description

Parse Server before 8.6.99 and 9.0.0 before 9.10.3-alpha.2 evaluates checks against the target account during a user update before authorizing the caller, and reflects their outcome in the response. An unauthorized caller, with or without a session, can confirm guessed usernames or emails and, when passwordPolicy.maxPasswordHistory or doNotAllowUsername is set, guessed current or previous passwords, bypassing account lockout.
