CVE-2026-81019

wolfProvider before 1.2.2 generates the 8-byte explicit AES-GCM nonce once when the TLS write key is set and never increments it per record. As a result every TLS 1.2 and DTLS 1.2 AES-GCM record within a connection is encrypted under an identical key and nonce pair. Reusing a GCM key and nonce...

CVE-2026-81020 wolfEngine reuses the AES-GCM nonce on every TLS 1.2 / DTLS 1.2 record

wolfEngine before 1.4.1 generates the 8-byte explicit AES-GCM nonce once when the TLS write key is set and never increments it per record. As a result every TLS 1.2 and DTLS 1.2 AES-GCM record within a connection is encrypted under an identical key and nonce pair. Reusing a GCM key and nonce...

CVE-2026-81019 wolfProvider reuses the AES-GCM nonce on every TLS 1.2 / DTLS 1.2 record

wolfProvider before 1.2.2 generates the 8-byte explicit AES-GCM nonce once when the TLS write key is set and never increments it per record. As a result every TLS 1.2 and DTLS 1.2 AES-GCM record within a connection is encrypted under an identical key and nonce pair. Reusing a GCM key and nonce...

PT-2026-83143

Name of the Vulnerable Software and Affected Versions wolfProvider versions prior to 1.2.2 Description The software generates the 8-byte explicit AES-GCM nonce only once when the TLS write key is set and fails to increment it for each record. Consequently, every TLS 1.2 and DTLS 1.2 AES-GCM recor...

CVE-2026-50577

ePA 3.x Integration implements the authorization workflow and writes Medical Information Objects to Germany's electronic patient record. Prior to 1.3.0, ePA 3.x Integration leaves requestcounter unchanged in app/vau/VAUProtokoll.py while constructing VAU messages. The frozen client request counte...

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...

CVE-2026-50577 ePA 3.x Integration: AES-GCM Nonce Reuse via Frozen VAU Request Counter

ePA 3.x Integration implements the authorization workflow and writes Medical Information Objects to Germany's electronic patient record. Prior to 1.3.0, ePA 3.x Integration leaves requestcounter unchanged in app/vau/VAUProtokoll.py while constructing VAU messages. The frozen client request counte...

CVE-2016-10213: Exposure of Sensitive Information to an Unauthorized Actor

A10 AX1030 and possibly other devices with software before 2.7.2-P8 uses random GCM nonce generations, which makes it easier for remote attackers to obtain the authentication key and spoof data by leveraging a reused nonce in a session and a "forbidden attack," a similar issue to CVE-2016-0270...
