CVE-2019-15620
Improper access control in Nextcloud Talk 6.0.3 leaks the existance and the name of private conversations when linked them to another shared item via the projects feature.
Does this matter?
Lower severity and a low EPSS score (0.77%). Track it; it rarely justifies an emergency change on its own.
