{"id":"CVE-2026-75930","state":"PUBLISHED","title":"FundEngine <= 1.8.1 - Missing Authorization to Authenticated (Subscriber+) Arbitrary Post Modification via 'campaign_post' Parameter","description":"The FundEngine – Donation and Crowdfunding Platform plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 1.8.1. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to modify arbitrary posts and pages — overwriting title and content, and seizing ownership by supplying an attacker-controlled post_author integer that bypasses wp_kses_post sanitization. The wp_rest nonce required by the handler is trivially obtainable by any logged-in user via /wp-admin/admin-ajax.php?action=rest-nonce and therefore does not constitute an authorization barrier.","publishedAt":"2026-08-25T03:27:05.464Z","updatedAt":"2026-08-25T15:19:49.192Z","severity":{"score":4.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["roxnor FundEngine – Donation and Crowdfunding Platform"],"affected":[{"vendor":"roxnor","product":"FundEngine – Donation and Crowdfunding Platform","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.8.1","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/08057fa2-90e1-4537-a828-a2c5902b348c?source=cve","https://plugins.trac.wordpress.org/browser/wp-fundraising-donation/tags/1.8.1/apps/content.php#L1228","https://plugins.trac.wordpress.org/browser/wp-fundraising-donation/tags/1.8.1/apps/content.php#L1195","https://plugins.trac.wordpress.org/browser/wp-fundraising-donation/tags/1.8.1/apps/content.php#L289","https://plugins.trac.wordpress.org/changeset?reponame=&old=3656562%40wp-fundraising-donation&new=3656562%40wp-fundraising-donation"],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-29T20:12:58.252Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/75xxx/CVE-2026-75930.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-75930","state":"PUBLISHED","datePublished":"2026-08-25T03:27:05.464Z","dateUpdated":"2026-08-25T15:19:49.192Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-08-18T15:43:07.095Z"},"containers":{"cna":{"title":"FundEngine <= 1.8.1 - Missing Authorization to Authenticated (Subscriber+) Arbitrary Post Modification via 'campaign_post' Parameter","descriptions":[{"lang":"en","value":"The FundEngine – Donation and Crowdfunding Platform plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 1.8.1.
