This is due to the plugin registering the 'build-app-online-update-vendor-product' AJAX action via wp_ajax_nopriv_ without proper authentication checks, capability verification, or nonce validation in the update_vendor_product() function. The function accepts a user-supplied post ID from the request and calls wp_update_post() to modify the post_author field without validating whether the user has permission to modify the specified post. This makes it possible for unauthenticated attackers to modify the post_author of arbitrary posts to 0 (orphaning posts from their legitimate authors), or for authenticated attackers to claim ownership of any post by setting themselves as the author."}],"title":"Build App Online <= 1.0.23 - Missing Authorization to Arbitrary Post Author Modification via 'build-app-online-update-vendor-product' AJAX Action","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/51564b26-0d7c-4499-9f5a-84f76c5a5e8a?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/build-app-online/trunk/admin/class-build-app-online-admin.php#L565"},{"url":"https://plugins.trac.wordpress.org/browser/build-app-online/tags/1.0.23/admin/class-build-app-online-admin.php#L565"},{"url":"https://plugins.trac.wordpress.org/browser/build-app-online/trunk/admin/class-build-app-online-admin.php#L556"},{"url":"https://plugins.trac.wordpress.org/browser/build-app-online/tags/1.0.23/admin/class-build-app-online-admin.php#L556"},{"url":"https://plugins.trac.wordpress.org/browser/build-app-online/trunk/includes/class-build-app-online.php#L233"},{"url":"https://plugins.trac.wordpress.org/browser/build-app-online/tags/1.0.23/includes/class-build-app-online.php#L233"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-862 Missing Authorization","cweId":"CWE-862","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:L/A:N","baseScore":5.3,"baseSeverity":"MEDIUM"}}],"credits":[{"lang":"en","type":"finder","value":"Ronnachai Sretawat Na Ayutaya"},{"lang":"en","type":"finder","value":"Ronnachai Chaipha"}],"timeline":[{"time":"2026-03-20T15:10:32.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-03-23T15:17:54.772965Z","id":"CVE-2026-3651","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":"2026-03-23T15:54:48.928Z"}}]}}
