CVE-2026-50577

In ePA 3.x Integration (fbeta-GmbH), request_counter is left unchanged in app/vau/VAUProtokoll.py, causing the server to reuse AES-GCM nonce/key pairs across responses. This enables a network attacker to recover plaintext XORs, exploit the Joux forbidden attack to recover the GHASH key, forge mes...

libssh: libssh: integrity downgrade via OpenSSL AES-GCM tag verification

A flaw was found in libssh. Incorrect AES-GCM finalization checks in builds using the OpenSSL backend can effectively remove integrity protection, allowing an in-path attacker to modify plaintext on the wire without detection...

PYSEC-2026-3773

opensslencrypt versions before 1.4.0 contain an authentication bypass vulnerability in pqc.py where AES-GCM decryption failures trigger fallback to unauthenticated AES-CTR mode. Attackers can modify ciphertext in transit to bypass integrity verification and perform bit-flipping attacks without...

CVE-2026-74901

The Python package openssl_encrypt (versions before 1.4.0) has a flaw in pqc.py : when AES-GCM decryption fails, the code silently falls back to unauthenticated AES-CTR mode. This removes integrity verification, allowing an attacker with network access to modify ciphertext in transit via bit-flip...

openssl: Incorrect Tag Processing for Empty Messages in AES-GCM-SIV and AES-SIV modes

A flaw was found in OpenSSL. The implementations of AES-SIV Advanced Encryption Standard - SIV and AES-GCM-SIV Advanced Encryption Standard - Galois/Counter Mode - SIV incorrectly process authentication tags for empty messages. This vulnerability allows a remote attacker to forge empty messages...
