CVE-2026-94419

The wolfSSL library (releases v5.3.0 through v5.9.2 ) is vulnerable to client session cache reference poisoning. Due to missing checks on the process-global SessionCache , an attacker can overwrite a client-side entry by providing a matching TLS 1.2 session ID sent in clear. This allows an attack...

CVE-2026-94419 Client session cache reference poisoning allows resumption with wrong server

Without NOSESSIONCACHEREF, wolfSSLgetsession does not return a session object but a ClientSession reference of the form row, index, hashsessionID into the process-global SessionCache, and ClientSessionToSession validates it against that hash alone. Because the TLS 1.2 session ID is chosen by the...
