CVE-2021-33491
OX App Suite through 7.10.5 allows Directory Traversal via ../ in an OOXML or ODF ZIP archive, because of the mishandling of relative paths in mail addresses in conjunction with auto-configuration DNS records.
Does this matter?
Lower severity and a low EPSS score (2.52%). Track it; it rarely justifies an emergency change on its own.
