CVE-2026-21587 Sep 15, 17:00 HIGH This Week

Improper authorization in Atlassian Jira Service Management Data Center 11.3.0 through 11.3.10 lets an authenticated, low-privileged attacker reach functionality and data they should not be able to access, with the vendor scoring it 7.1 in CVSS 4.0 (AV:N/AC:L/PR:L/UI:N/VI:H). Atlassian states the flaw was discovered through its own penetration-testing program and that the impact could extend from exposure of sensitive resources to arbitrary code execution, though the published CVSS 4.0 vector only credits a high integrity impact and rates confidentiality and availability as none. No CISA KEV listing, EPSS score, or public exploit code was provided in the source data, so at time of analysis this should be treated as a confirmed but not yet observed-in-the-wild authorization bypass; patched versions (11.3.11 and later) are already available.
