{"id":"CVE-2026-4949","state":"PUBLISHED","title":"ProfilePress <= 4.16.12 - Missing Authorization to Authenticated (Subscriber+) Inactive Membership Plan Subscription","description":"The Paid Membership Plugin, Ecommerce, User Registration Form, Login Form, User Profile & Restrict Content – ProfilePress plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 4.16.12. This is due to the 'process_checkout' function not properly enforcing the plan active status check when a 'change_plan_sub_id' parameter is provided. This makes it possible for authenticated attackers, with Subscriber-level access and above, to subscribe to inactive membership plans by supplying an arbitrary 'change_plan_sub_id' value in the checkout request.","publishedAt":"2026-04-15T22:26:05.515Z","updatedAt":"2026-04-16T14:19:21.197Z","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":["properfraction Paid Membership Plugin, Ecommerce, User Registration Form, Login Form, User Profile & Restrict Content – ProfilePress"],"affected":[{"vendor":"properfraction","product":"Paid Membership Plugin, Ecommerce, User Registration Form, Login Form, User Profile & Restrict Content – ProfilePress","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"4.16.12","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/4cc29d32-2727-42df-bd42-2caf0f182c0e?source=cve","https://plugins.trac.wordpress.org/browser/wp-user-avatar/tags/4.16.10/src/Membership/Controllers/CheckoutController.php#L223","https://plugins.trac.wordpress.org/browser/wp-user-avatar/tags/4.16.10/src/Membership/Controllers/CheckoutController.php#L239","https://plugins.trac.wordpress.org/browser/wp-user-avatar/tags/4.16.10/src/Membership/Models/Subscription/SubscriptionEntity.php#L461","https://plugins.trac.wordpress.org/browser/wp-user-avatar/tags/4.16.10/src/Admin/SettingsPages/Membership/PlansPage/SettingsPage.php#L107","https://plugins.trac.wordpress.org/browser/wp-user-avatar/tags/4.16.10/src/Admin/SettingsPages/Membership/views/add-edit-plan.php#L24","https://plugins.trac.wordpress.org/changeset/3497425/wp-user-avatar#file14"],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-29T20:12:16.098Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/4xxx/CVE-2026-4949.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-4949","state":"PUBLISHED","datePublished":"2026-04-15T22:26:05.515Z","dateUpdated":"2026-04-16T14:19:21.197Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-03-27T06:15:12.658Z"},"containers":{"cna":{"title":"ProfilePress <= 4.16.12 - Missing Authorization to Authenticated (Subscriber+) Inactive Membership Plan Subscription","descriptions":[{"lang":"en","value":"The Paid Membership Plugin, Ecommerce, User Registration Form, Login Form, User Profile & Restrict Content – ProfilePress plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 4.16.12.
