CVE-2026-75803
OpenSSL 's EVP_Cipher() function, a one-shot AEAD encryption/decryption API, skips authentication tag verification when an empty ciphertext is passed for ChaCha20-Poly1305 and AES-OCB ciphers, yet still returns success. Callers expecting a valid AEAD tag check may therefore accept forged messages...
