CVE-2026-67449

Portabase is a database backup and restore tool for PostgreSQL, MySQL, MsSQL, MariaDB, Firebird SQL, SQLite, MongoDB, Redis, Files and Docker Volume. Prior to version 1.21.2, a path traversal in the TUS upload webhook handler (app/api/tus/hooks/route.ts) allowed an unauthenticated attacker to overwrite arbitrary files under the private data directory, including /data/private/keys/master_key.bin (the AES-256-GCM master key). This issue has been patched in version 1.21.2.
