CVE-2020-36235Network attack vector

Unauthenticated metadata disclosure via mobile site view

Published Feb 14, 2021 · Updated Sep 16, 2024

Information disclosure in Atlassian Jira Server and Data Center before 8.13.2 and in 8.14.0 allows remote attackers to view private names. The mobile site view returns custom-field and custom-SLA names associated with privately linked tickets without enforcing their access restrictions. No authentication is required, but the disclosed content is limited to those names; ticket contents, modification, and service interruption are not reported.
