| Doc Text: |
A flaw was found in SimpleJWT, a PHP library for JSON Web Tokens. An unauthenticated attacker can exploit this vulnerability by tampering with JSON Web Encryption (JWE) headers when Password-Based Key Derivation Function 2 (PBES2) algorithms are in use. This can lead to a Denial of Service (DoS) if an application calls JWE::decrypt() on attacker-controlled JWEs, making the affected application unavailable.
