| Summary | openssl-encrypt has no owner verification on key revocation — any client can revoke any key ### Summary 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`. ### Impact 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. ### Recommended Fix - Add an ownership check: verify `client_id == key.owner_client_id` before allowing revocation - Return 403 Forbidden if the requesting client does not own the key ### Fix Fixed 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. |
