{"id":"CVE-2026-1303","state":"PUBLISHED","title":"MailChimp Campaigns <= 3.2.4 - Missing Authorization to Authenticated (Subscriber+) MailChimp App Disconnection","description":"The MailChimp Campaigns plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 3.2.4. This is due to missing capability checks on the `mailchimp_campaigns_manager_disconnect_app` function that is hooked to the AJAX action of the same name. This makes it possible for authenticated attackers, with Subscriber-level access and above, to disconnect the site from its MailChimp synchronization app, disrupting automated email campaigns and marketing integrations.","publishedAt":"2026-02-14T06:42:33.704Z","updatedAt":"2026-04-08T17:19:59.377Z","severity":{"score":5.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["matthieuscarset MailChimp Campaigns"],"affected":[{"vendor":"matthieuscarset","product":"MailChimp Campaigns","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"3.2.4","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/c2057ec2-9f03-4ae9-b200-aa5a318b461e?source=cve","https://plugins.trac.wordpress.org/browser/olalaweb-mailchimp-campaign-manager/trunk/mailchimp-campaigns-manager.php#L636","https://plugins.trac.wordpress.org/browser/olalaweb-mailchimp-campaign-manager/tags/3.2.4/mailchimp-campaigns-manager.php#L636"],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-29T20:11:10.572Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/1xxx/CVE-2026-1303.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-1303","state":"PUBLISHED","datePublished":"2026-02-14T06:42:33.704Z","dateUpdated":"2026-04-08T17:19:59.377Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-01-21T18:58:37.641Z"},"containers":{"cna":{"title":"MailChimp Campaigns <= 3.2.4 - Missing Authorization to Authenticated (Subscriber+) MailChimp App Disconnection","descriptions":[{"lang":"en","value":"The MailChimp Campaigns plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 3.2.4.
