CVE-2021-29483
The 'wikiconfig' API leaked the value of private configuration variables set through the ManageWiki variable to all users.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.21%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
