{"id":"CVE-2026-104010","aliases":[],"url":"https://o3.security/vulnerability/CVE-2026-104010","summary":"The WPSyncSheets For Contact Form 7 – CF7 Google Sheets Connector & Save to Database plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including,…","details":"The WPSyncSheets For Contact Form 7 – CF7 Google Sheets Connector & Save to Database plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 1.8.0 via the 'any non-system CF7 field (e.g., your-message)' parameter parameter. This is due to insufficient sanitization of CF7 submission field values before database storage and the absence of an allowed_classes restriction on maybe_unserialize() during admin retrieval. This makes it possible for unauthenticated attackers to execute code on the server. Successful exploitation of the remote code execution gadget chain requires that a Google Sheets access token be configured in the plugin (its primary advertised feature), as this triggers autoloading of the bundled Monolog 2.10.0 library whose classes form the exploitable gadget chain; however, the underlying PHP Object Injection occurs regardless.","published":"2026-11-06T12:17:15.827","modified":"2026-11-06T12:17:15.973","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/contactsheets-lite/tags/1.8.0/includes/class-wpsslc-google-api-functions.php#L157"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/contactsheets-lite/tags/1.8.0/includes/class-wpsslc-service.php#L114"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/contactsheets-lite/tags/1.8.0/includes/class-wpsslc-service.php#L184"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/contactsheets-lite/tags/1.8.0/includes/entry/class-wpsslc-cf7-entries-table.php#L459"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/contactsheets-lite/tags/1.8.0/includes/entry/class-wpsslc-single-entry.php#L131"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/changeset/3783292/contactsheets-lite/trunk/includes/entry/class-wpsslc-cf7-entries-table.php"},{"type":"WEB","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/366e20df-4cb2-4ba1-93fd-11552faa1a32?source=cve"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-11-06T12:17:15.973"}}
