CVE-2024-21492
All versions of the package github.com/greenpau/caddy-security are vulnerable to Insufficient Session Expiration due to improper user session invalidation upon clicking the "Sign Out" button.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.71%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
All versions of the package github.com/greenpau/caddy-security are vulnerable to Insufficient Session Expiration due to improper user session invalidation upon clicking the "Sign Out" button. User sessions remain valid even after requests are sent to /logout and /oauth2/google/logout. Attackers who gain access to an active but supposedly logged-out session can perform unauthorized actions on behalf of the user.
