Last modified Jun 16, 2026

CVE-2009-4269 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 1.48% chance of exploitation in the next 30 days.
