{"id":"CVE-2026-9842","state":"PUBLISHED","title":"Backstage <= 1.4.2 - Unauthenticated Privilege Escalation via Permissive Demo Role Capabilities","description":"The Backstage - Customizer Demo Access plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 1.4.2. 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.","publishedAt":"2026-07-08T04:30:49.525Z","updatedAt":"2026-07-08T13:01:09.142Z","severity":{"score":7.5,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["pixelgrade Backstage – Customizer Demo Access"],"affected":[{"vendor":"pixelgrade","product":"Backstage – Customizer Demo Access","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.4.2","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/5bcf1f02-0946-4e96-a81b-00c7c48d64b3?source=cve","https://plugins.trac.wordpress.org/browser/backstage/tags/1.4.2/includes/class-Backstage.php#L154","https://plugins.trac.wordpress.org/browser/backstage/tags/1.4.2/includes/class-Backstage.php#L348"],"weaknesses":["CWE-269"],"ingestedAt":"2026-10-29T20:13:52.441Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/9xxx/CVE-2026-9842.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-9842","state":"PUBLISHED","datePublished":"2026-07-08T04:30:49.525Z","dateUpdated":"2026-07-08T13:01:09.142Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-05-28T13:26:31.589Z"},"containers":{"cna":{"title":"Backstage <= 1.4.2 - Unauthenticated Privilege Escalation via Permissive Demo Role Capabilities","descriptions":[{"lang":"en","value":"The Backstage - Customizer Demo Access plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 1.4.2.
