CVE-2021-30141
Module/Settings/UserExport.php in Friendica through 2021.01 allows settings/userexport to be used by anonymous users, as demonstrated by an attempted access to an array offset on a value of type null, and excessive memory consumption.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.52%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
