Does this matter?

Lower severity and a low EPSS score (0.21%). Track it; it rarely justifies an emergency change on its own.

Description

The extension fails to properly validate the expiration of a client-supplied JWT token, allowing an attacker in control of a valid API key to authenticate with an expired token. Exploitation requires the attacker to already be in control of the SYSSY project's API key.
