This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This is exploitable by Subscriber-level users because WordPress core's sanitize_text_field() preserves HTML-entity-encoded payloads (e.g., an iframe srcdoc attribute), allowing the encoded string to be stored as a display name without requiring the unfiltered_html capability, and the plugin subsequently decodes it server-side before rendering.","state":0,"publishedAt":"2026-09-25T06:39:57.796+00:00","modifiedAt":"2026-09-25T13:00:16.015+00:00","affected":[{"ecosystem":"Vendor product","name":"Better Messages – Chat Rooms, Group Chat, Private Messages & AI Chat Bots","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"wordplus\",\n                    \"product\": \"Better Messages – Chat Rooms, Group Chat, Private Messages & AI Chat Bots\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"lessThanOrEqual\": \"3.0.4\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","score":6.4,"severity":"MEDIUM"}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/f4f5a268-7e7f-4dbe-823a-a17ac0f52928?source=cve","https://plugins.trac.wordpress.org/browser/bp-better-messages/tags/3.0.3/inc/functions.php#L2276","https://plugins.trac.wordpress.org/browser/bp-better-messages/tags/3.0.3/inc/functions.php#L1117","https://plugins.trac.wordpress.org/changeset?old_path=bp-better-messages%2Ftags%2F3.0.3%2Faddons%2Fbuddyboss.php&new_path=bp-better-messages%2Ftags%2F3.0.5%2Faddons%2Fbuddyboss.php"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-94376","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-94376","identifiers":["CVE-2026-94376"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
