CVE-2020-29451Network attack vector

Authenticated project enumeration via report page

Published Feb 15, 2021 · Updated Sep 16, 2024

Information disclosure in Atlassian Jira Server and Data Center allows remote authenticated users to enumerate projects through a report page. The Jira Projects plugin report page returns project enumeration results without enforcing the intended visibility restriction; Atlassian has not disclosed the responsible code path. A low-privileged account can discover project names but receives no reported ability to read issue contents, alter data, or interrupt service.
