Summary
CAT through 3.1.0 Session Cookie Forgery via Unkeyed hashCode Checksum
Details

CAT uses Java String.hashCode as the sole integrity check for session cookies without server-side keying, allowing attackers to forge valid checksums offline. Attackers can set the x-forwarded-for header to bypass IP binding validation and create admin sessions with full configuration access.
