Does this matter?
Lower severity and a low EPSS score (1.43%). Track it; it rarely justifies an emergency change on its own.
Description
The password hash generation algorithm in the BUILTIN authentication functionality for Apache Derby before 10.6.1.0 performs a transformation that reduces the size of the set of inputs to SHA-1, which produces a small search space that makes it easier for local and possibly remote attackers to crack passwords by generating hash collisions, related to password substitution.
