      Someone not verifying the signature at all is not a mistake where you can blame the JWT spec itself.

        They did verify the signature, and it was correct according to the &quot;none&quot; algorithm.

          Argh, I missed that it actually uses the &quot;none&quot; algorithm. Yeah, the existence of that option is extremely dumb and it shouldn&#x27;t be possible to use that. I misread the post and thought it was a regular JWT, but they simply didn&#x27;t validate it.
