The revoke_key method in openssl_encrypt_server/modules/keyserver/service.py at lines 195-270 accepts a client_id parameter but never verifies that the requesting client is the same as key.owner_client_id.
Any authenticated client can revoke any other client's key, as long as they provide a valid revocation signature. While the signature requirement mitigates this somewhat (you need the private key to sign), the lack of ownership check is a defense-in-depth gap.
client_id == key.owner_client_id before allowing revocationFixed in commit 05e45f3 on branch releases/1.4.x — added documentation that ML-DSA signature verification IS the cryptographic ownership check; added info-level logging on successful verification.
