{"cve":"CVE-2026-3645","nvd":{"published":"2026-03-21T04:17:33.017","modified":"2026-06-17T10:43:55.057","status":"Deferred","description":"The Punnel – Landing Page Builder plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 1.3.1. 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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","score":5.3},"cwes":["CWE-862"],"references":["https://plugins.trac.wordpress.org/browser/punnel-landing-page-builder/tags/1.3.1/punnel.php#L118","https://plugins.trac.wordpress.org/browser/punnel-landing-page-builder/tags/1.3.1/punnel.php#L156","https://plugins.trac.wordpress.org/browser/punnel-landing-page-builder/tags/1.3.1/punnel.php#L179","https://plugins.trac.wordpress.org/browser/punnel-landing-page-builder/tags/1.3.1/punnel.php#L403","https://plugins.trac.wordpress.org/browser/punnel-landing-page-builder/tags/1.3.1/punnel.php#L410"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:26:19.218427112+00:00"},"epss":{"cve":"CVE-2026-3645","score":0.00304,"percentile":0.23185,"date":"2026-11-01"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
