CVE-2026-39659

Rejected missing-authorization claim

Published Apr 8, 2026 · Updated Apr 8, 2026

Ultimate Member 2.11.3 and earlier was assigned a missing-authorization issue, but the assigning CNA has rejected the CVE. The withdrawn record never identified a vulnerable endpoint, function, resource, or authorization check, and its sole Patchstack reference now reports that the entry was removed. Because the identifier is rejected and no concrete mechanism remains published, no attacker gate or confirmed security consequence can be attributed to it.
