CVE-2019-15619
Improper neutralization of file names, conversation names and board names in Nextcloud Server 16.0.3, Nextcloud Talk 6.0.3 and Nextcloud Deck 0.6.5 causes an XSS when linking them with each others in a project.
Does this matter?
Lower severity and a low EPSS score (0.84%). Track it; it rarely justifies an emergency change on its own.
