CVE-2026-59163 Mnemosyne has JWT signature verification bypass sync server that allows authentication bypass

Mnemosyne is a memory layer for artificial intelligence agents. Prior to v3.10.1, the auth check in mnemosyne/core/syncserver.py parsed the JWT's header and payload using base64 decoding, then passed the token to a jwt library call with options that effectively disabled signature verification. Th...
