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."}], "title": "WPSyncSheets For Contact Form 7 <= 1.8.0 - Unauthenticated PHP Object Injection to Remote Code Execution via Untrusted CF7 Submission Field via maybe_unserialize()", "references": [{"url": "https://www.wordfence.com/threat-intel/vulnerabilities/id/366e20df-4cb2-4ba1-93fd-11552faa1a32?source=cve"}, {"url": "https://plugins.trac.wordpress.org/browser/contactsheets-lite/tags/1.8.0/includes/entry/class-wpsslc-cf7-entries-table.php#L459"}, {"url": "https://plugins.trac.wordpress.org/browser/contactsheets-lite/tags/1.8.0/includes/class-wpsslc-service.php#L114"}, {"url": "https://plugins.trac.wordpress.org/browser/contactsheets-lite/tags/1.8.0/includes/class-wpsslc-service.php#L184"}, {"url": "https://plugins.trac.wordpress.org/browser/contactsheets-lite/tags/1.8.0/includes/entry/class-wpsslc-single-entry.php#L131"}, {"url": "https://plugins.trac.wordpress.org/browser/contactsheets-lite/tags/1.8.0/includes/class-wpsslc-google-api-functions.php#L157"}, {"url": "https://plugins.trac.wordpress.org/changeset/3783292/contactsheets-lite/trunk/includes/entry/class-wpsslc-cf7-entries-table.php"}], "problemTypes": [{"descriptions": [{"lang": "en", "description": "CWE-502 Deserialization of Untrusted Data", "cweId": "CWE-502", "type": "CWE"}]}], "metrics": [{"cvssV3_1": {"version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H", "baseScore": 7.5, "baseSeverity": "HIGH"}}], "credits": [{"lang": "en", "type": "finder", "value": "GivMeInJ"}], "timeline": [{"time": "2026-11-03T13:34:33.000Z", "lang": "en", "value": "Vendor Notified"}, {"time": "2026-11-05T22:08:55.000Z", "lang": "en", "value": "Disclosed"}]}}}
