This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The heatmap recording endpoint accepts unauthenticated requests protected only by a nonce that any visitor can freely obtain via the public opti_behavior_refresh_nonces AJAX action, removing any practical barrier to injecting the malicious payload.","state":0,"publishedAt":"2026-10-16T05:30:23.365+00:00","modifiedAt":"2026-10-16T14:39:04.367+00:00","affected":[{"ecosystem":"Vendor product","name":"Opti-Behavior – Self-Hosted Heatmaps, Funnels, A/B Testing & Smart Insights","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"optiuser\",\n                    \"product\": \"Opti-Behavior – Self-Hosted Heatmaps, Funnels, A/B Testing & Smart Insights\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"lessThanOrEqual\": \"1.9.2.1\",\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:C/C:L/I:L/A:N","score":7.2,"severity":"HIGH"}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/6c631593-4857-46c8-80b3-d028524cb86c?source=cve","https://plugins.trac.wordpress.org/browser/opti-behavior/tags/1.9.0/assets/js/metabox-analytics.js#L668","https://plugins.trac.wordpress.org/browser/opti-behavior/tags/1.9.0/admin/class-opti-behavior-heatmap-ajax-handler.php#L2656","https://plugins.trac.wordpress.org/browser/opti-behavior/tags/1.9.0/admin/class-opti-behavior-heatmap-ajax-handler.php#L1603","https://plugins.trac.wordpress.org/browser/opti-behavior/tags/1.9.0/includes/class-opti-behavior-heatmap-session.php#L369","https://plugins.trac.wordpress.org/browser/opti-behavior/tags/1.9.0/admin/class-opti-behavior-heatmap-post-metabox.php#L1498","https://plugins.svn.wordpress.org/opti-behavior/","https://plugins.trac.wordpress.org/changeset/3738510/opti-behavior/trunk/assets/js/metabox-analytics.js"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-95809","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-95809","identifiers":["CVE-2026-95809"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
