Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Spring Security (spring-security-core) versions 5.7.0 through 5.7.22, 5.8.0 through 5.8.24, 6.3.0 through 6.3.15, 6.4.0 through 6.4.15, 6.5.0 before 6.5.10, and 7.0.0 before 7.0.5 are affected. Applications that use UserDetails isEnabled, isAccountNonExpired, or isAccountNonLocked to disable, expire, or lock users can have DaoAuthenticationProvider's timing attack defense bypassed for those users, which lets an attacker who can send login attempts tell disabled, expired, or locked accounts apart from other accounts. Upgrade to version 6.5.10 or 7.0.5, or the fixed release in your branch.
