Overview
org.springframework.security:spring-security-crypto is a spring-security-crypto library for Spring Security.
Affected versions of this package are vulnerable to Authentication Bypass by Primary Weakness in the BCryptPasswordEncoder.matches() function, which only takes the first 72 characters for comparison. Passwords longer than this will incorrectly return true when compared against other strings sharing the same first 72 characters, making them easier to brute force.
Note: Patches have also been issued for older versions of Enterprise Support packages.
