JSON Web Token Attacker

Summary: PortSwigger's BApp Store lists JOSEPH, a Burp Suite extension by Dennis Detering at version 1.0.2a, last updated 04 February 2022, that helps test applications using JavaScript Object Signing and Encryption, including JSON Web Tokens. PortSwigger notes the extension is written by a third party and makes no warranty about its quality or usefulness for any particular purpose.

Why it matters: JWT and JOSE handling is a common authentication surface, and the tooling your testers reach for to probe it is third-party code last updated in February 2022 that the vendor explicitly declines to vouch for.
