The value is passed through sanitize_text_field(), which does not strip serialized object syntax, then stored in the LearnPress session table and later fed to LP_Helper::maybe_unserialize() → unserialize() (without an allowed_classes restriction) by LP_Session_Handler::get() on subsequent requests. This makes it possible for unauthenticated attackers to inject a PHP Object.","state":0,"publishedAt":"2026-10-17T03:43:28.046+00:00","modifiedAt":"2026-10-18T11:22:46.937+00:00","affected":[{"ecosystem":"Vendor product","name":"LearnPress – WordPress LMS Plugin for Create and Sell Online Courses","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"thimpress\",\n                    \"product\": \"LearnPress – WordPress LMS Plugin for Create and Sell Online Courses\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"lessThanOrEqual\": \"4.4.10\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8,"severity":"CRITICAL"}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/3e28e008-0ec1-4262-9ac0-6170cf8b8bdf?source=cve","https://plugins.trac.wordpress.org/browser/learnpress/tags/4.4.9.1/inc/class-lp-session-handler.php#L373","https://plugins.trac.wordpress.org/browser/learnpress/tags/4.4.9.1/inc/class-lp-checkout.php#L377","https://plugins.trac.wordpress.org/browser/learnpress/tags/4.4.9.1/inc/class-lp-checkout.php#L523","https://plugins.trac.wordpress.org/browser/learnpress/tags/4.4.9.1/inc/class-lp-ajax.php#L21","https://plugins.trac.wordpress.org/changeset?reponame=&old=3750024%40learnpress&new=3750024%40learnpress"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-104736","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-104736","identifiers":["CVE-2026-104736"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
