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"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-11-06T15:11:06.810573Z","id":"CVE-2026-104010","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-11-06T15:15:50.427Z"}}]}}
