CVE-2021-26698
OX App Suite before 7.10.3-rev32 and 7.10.4 before 7.10.4-rev18 allows XSS via a code snippet (user-generated content) when a sharing link is created and the dl parameter is used.
Does this matter?
Lower severity and a low EPSS score (1.43%). Track it; it rarely justifies an emergency change on its own.
