CVE-2026-33204 High · 7.5 CWE-400 Mar 20, 2026
SimpleJWT has an Unauthenticated Denial of Service via JWE header tampering
SimpleJWT is a simple JSON web token library written in PHP. Prior to version 1.1.1, an unauthenticated attacker can perform a Denial of Service via JWE header tampering when PBES2 algorithms are used. Applications that call JWE::decrypt() on attacker-controlled JWEs using PBES2 algorithms are affected. This issue has been patched in version 1.1.1.
