CVE-2026-74877

openssl_encrypt versions before 1.4.0 contain a missing ownership verification flaw in the revoke_key method (keyserver/service.py, lines 195–270). The method accepts a client_id parameter but never verifies it matches key.owner_client_id, allowing any authenticated client to revoke another clien...

EUVD-2026-60096

opensslencrypt versions before 1.4.0 contain a missing ownership verification vulnerability in the revokekey method that allows authenticated clients to revoke any other client's key. Attackers can revoke arbitrary keys by providing a valid ML-DSA signature, bypassing the intended ownership...

CVE-2026-74876 openssl_encrypt before 1.4.0 Unverified Key Bundle Encryption

opensslencrypt versions before 1.4.0 contain a vulnerability in PublicKeyBundle.fromdict that creates key bundles from untrusted data without verifying signatures. Attackers can call fromdict followed by toidentity without signature verification to encrypt data using attacker-controlled public...

CVE-2026-74876

In openssl_encrypt before 1.4.0, PublicKeyBundle.from_dict() accepts untrusted key bundle data without signature verification. Attackers can craft a malicious bundle, call to_identity(), and encrypt secrets to an attacker-controlled public key, enabling confidential data exfiltration. CVSS 9.8 cr...

CVE-2026-74875 openssl_encrypt before 1.4.0 Schema Validation Bypass

opensslencrypt versions before 1.4.0 silently skip JSON schema validation when the jsonschema library is not installed, allowing malformed metadata to be accepted. Attackers can remove the jsonschema package or supply unknown metadata format versions to bypass all schema checks and process...
