Mitigation checklist

Recommended fix / mitigation

To mitigate this vulnerability, administrators should avoid using pgcrypto encryption and decryption operations with ciphers that are disabled by the system's OpenSSL configuration or local security policies. Organizations should proactively review their OpenSSL cipher policies to ensure required cryptographic algorithms are fully supported, or transition to robust, enabled algorithms within pgcrypto. Additionally, applications should treat all encrypted input as untrusted and independently validate data
