Security vulnerability(JWT token ) Web authentication

Hi all
JWT token does not expire when the admin logout of the UI, allowing potential unauthorized access by copying the token. This a security vulnerability that can be mitigated by setting a shorter expiration period for the token. However, the vulnerability still persists despite these measures. How to fix this issue?

The expiration is a concept of JWTs.

Note, that the JWT is deleted, when the admin log outs from the UI.

Possible actions out of the box:

  1. You can set a shorter lock timeout. See 7.6. WebUI Policies — privacyIDEA 3.10dev1 documentation

  2. You could reset the SECRET_KEY, that is used to sign the JWT, thus rendering issues JWTs invalid. See: 2.5. The Config File — privacyIDEA 3.10dev1 documentation
