CVE-2019-20404Network attack vector

Project-title disclosure via missing API authorization

Published Feb 6, 2020 · Updated Sep 16, 2024

Improper authorization in Atlassian Jira Server before 8.6.0 allows remote authenticated users to read inaccessible project titles. The REST API returns a project's title without enforcing the requester's project-view permission. Any authenticated account able to reach the affected API can enumerate titles for projects otherwise hidden from that account.
