This is due to the plugin assigning the `manage_options` capability to the `backstage_customizer_user` demo role, which is more permissive than necessary for Customizer-only demo access. This makes it possible for unauthenticated attackers to navigate beyond the Customizer and update arbitrary WordPress options such as `default_role`, leading to privilege escalation."}],"title":"Backstage <= 1.4.2 - Unauthenticated Privilege Escalation via Permissive Demo Role Capabilities","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/5bcf1f02-0946-4e96-a81b-00c7c48d64b3?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/backstage/tags/1.4.2/includes/class-Backstage.php#L154"},{"url":"https://plugins.trac.wordpress.org/browser/backstage/tags/1.4.2/includes/class-Backstage.php#L348"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-269 Improper Privilege Management","cweId":"CWE-269","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","baseScore":7.5,"baseSeverity":"HIGH"}}],"credits":[{"lang":"en","type":"finder","value":"Nabil Irawan"}],"timeline":[{"time":"2026-03-23T00:00:00.000Z","lang":"en","value":"Discovered"},{"time":"2026-07-07T16:30:36.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-07-08T13:00:54.003774Z","id":"CVE-2026-9842","options":[{"Exploitation":"none"},{"Automatable":"yes"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-07-08T13:01:09.142Z"}}]}}
