CVE-2020-36287Network attack vector

Gadget settings disclosure via missing permission check

Published Apr 9, 2021 · Updated Sep 16, 2024

Incorrect authorization in Jira Server and Jira Data Center before 8.13.5 and 8.14.0 through 8.15.0 allows remote attackers to read gadget settings. The Atlassian Gadgets dashboard preference REST resource returns stored gadget user-preference values without checking dashboard permissions. No authentication or user interaction is required, but a reachable anonymously accessible dashboard with configured gadgets is needed; the reported consequence is limited to disclosure of those settings.
