CVE-2023-2182
Under certain conditions when OpenID Connect is enabled on an instance, it may allow users who are marked as 'external' to become 'regular' users thus leading to privilege escalation for those users.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.04%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
