CVE-2023-28845

Name of the Vulnerable Software and Affected Versions Nextcloud Talk versions prior to 14.0.9 Nextcloud Talk versions prior to 15.0.4

Description The issue arises from the talk app not properly filtering access to a conversation's member list. This allows an attacker to gain information about the members of a Talk conversation, even if they are not members themselves.

Recommendations For versions prior to 14.0.9, upgrade to 14.0.9. For versions prior to 15.0.4, upgrade to 15.0.4. As a temporary workaround, consider restricting access to the conversation member list until a patch is available.
