Unauthenticated group membership disclosure via membersOf JQL
Published Apr 1, 2021 · Updated Sep 16, 2024
Information disclosure in Atlassian Jira Server and Data Center allows remote attackers to enumerate groups and members through JQL. The membersOf search function resolves an attacker-supplied group name against publicly searchable issue fields and returns matches that reveal group existence and account membership. No authentication is required, but disclosure depends on group members being assigned to a publicly visible issue field and is limited to group existence and membership data.
