CVE-2026-33306 bcrypt-ruby has an Integer Overflow that Causes Zero Key-Strengthening Iterations at Cost=31 on JRuby

bcrypt-ruby is a Ruby binding for the OpenBSD bcrypt password hashing algorithm. Prior to version 3.1.22, an integer overflow in the Java BCrypt implementation for JRuby can cause zero iterations in the strengthening loop. Impacted applications must be setting the cost to 31 to see this happen. T...

CVE-2026-33306

CVE-2026-33306 affects bcrypt-ruby (JRuby Java BCrypt implementation) where a signed 32-bit integer overflow at cost=31 causes the key-strengthening loop to run zero iterations, collapsing bcrypt from 2^31 rounds to effectively constant time. This leads to weaker hashes that may be exploitable. T...
