The save_config() function, which handles the 'punnel_save_config' AJAX action, lacks any capability check (current_user_can()) and nonce verification. This makes it possible for authenticated attackers, with Subscriber-level access and above, to overwrite the plugin's entire configuration including the API key via a POST request to admin-ajax.php. Once the API key is known (because the attacker set it), the attacker can use the plugin's public API endpoint (sniff_requests() at /?punnel_api=1) — which only validates requests by comparing a POST token against the stored api_key — to create, update, or delete arbitrary posts, pages, and products on the site." } ], "title": "Punnel <= 1.3.1 - Missing Authorization to Authenticated (Subscriber+) Settings Update via 'punnel_save_config' AJAX Action", "references": [ { "url": "https://www.wordfence.com/threat-intel/vulnerabilities/id/b6f54ca4-297f-44e8-8bb3-25cdc52f94ff?source=cve" }, { "url": "https://plugins.trac.wordpress.org/browser/punnel-landing-page-builder/trunk/punnel.php#L410" }, { "url": "https://plugins.trac.wordpress.org/browser/punnel-landing-page-builder/tags/1.3.1/punnel.php#L410" }, { "url": "https://plugins.trac.wordpress.org/browser/punnel-landing-page-builder/trunk/punnel.php#L403" }, { "url": "https://plugins.trac.wordpress.org/browser/punnel-landing-page-builder/tags/1.3.1/punnel.php#L403" }, { "url": "https://plugins.trac.wordpress.org/browser/punnel-landing-page-builder/trunk/punnel.php#L179" }, { "url": "https://plugins.trac.wordpress.org/browser/punnel-landing-page-builder/tags/1.3.1/punnel.php#L179" }, { "url": "https://plugins.trac.wordpress.org/browser/punnel-landing-page-builder/trunk/punnel.php#L118" }, { "url": "https://plugins.trac.wordpress.org/browser/punnel-landing-page-builder/tags/1.3.1/punnel.php#L118" }, { "url": "https://plugins.trac.wordpress.org/browser/punnel-landing-page-builder/trunk/punnel.php#L156" }, { "url": "https://plugins.trac.wordpress.org/browser/punnel-landing-page-builder/tags/1.3.1/punnel.php#L156" } ], "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": "Phong Nguyen" } ], "timeline": [ { "time": "2026-03-20T15:09:24.000Z", "lang": "en", "value": "Disclosed" } ] }, "adp": [ { "metrics": [ { "other": { "type": "ssvc", "content": { "timestamp": "2026-03-24T13:55:38.136142Z", "id": "CVE-2026-3645", "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": "2026-03-24T13:55:47.127Z" } } ] } }
