spring-security-crypto is vulnerable to Improper Authentication
74
High Risk

spring-security-cryptoTL;DR
Affected versions of this package are vulnerable to improper password verification in BCryptPasswordEncoder.matches(CharSequence, String). When a password exceeds 72 characters, only the first 72 characters are considered for comparison. As a result, passwords that share the same initial 72 characters will incorrectly be treated as identical, potentially allowing authentication bypass.

You are affected if you are using a version that falls within the vulnerable range.
