Technical details
A session management vulnerability (CWE-613) exists in pyLoad where user permissions are not re-validated for active sessions following an administrative change. When an administrator modifies or revokes a user's privileges, the application fails to invalidate existing session tokens or refresh the permission set associated with those tokens. Consequently, a user with an established session can continue to perform actions and access resources that their updated permissions should prohibit. The attack requires a pre-existing valid session to be active during the permission change. A fix was identified in commit e95804fb0d06cbb07d2ba380fc494d9ff89b68c1.
