Miggo AIMiggo AIMiggo AIRoot Cause AnalysisThe vulnerability stems from using SHA-384 pre-hashing without salt before bcrypt, as shown in the commit diff where these functions were replaced with direct password_hash/password_verify. The deprecated hashDanger() and verifyDanger() methods in the patched code represent the old vulnerable implementation. This implementation allowed attackers to exploit externally leaked SHA-384 hashes to bypass bcrypt's protection through password shucking, as described in the referenced security advisories and blog posts.
