{"schema":"threatline.record/2","record":{"id":"CVE-2026-107748","aliases":[],"summary":"User Profile Builder <= 4.0.3 - Authenticated (Subscriber+) Stored Cross-Site Scripting via 'display_name' Parameter","details":"The User Profile Builder – Beautiful User Registration Forms, User Profiles & User Role Editor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'display_name' parameter in all versions up to, and including, 4.0.3 due to insufficient input sanitization and output escaping. 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. The payload persists in wp_comments.comment_author independently of the user account, so removing or changing the attacker's display name after the comment is posted does not neutralize the stored script.","categories":["Unclassified"],"product":"User Profile Builder – Beautiful User Registration Forms, User Profiles & User Role Editor","vendor":"cozmoslabs","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-107748","source_modified_at":"2026-10-16T14:39:04.655Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"User Profile Builder – Beautiful User Registration Forms, User Profiles & User Role Editor","vendor":"cozmoslabs","versions":[{"version":"0","status":"affected","lessThanOrEqual":"4.0.3","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":6.4,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00201,"percentile":0.09483,"score_date":"2026-10-23"},"published_at":"2026-10-16T05:30:20.376Z","modified_at":"2026-10-16T14:39:04.655Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-107748","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-16T14:39:04.655Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-107748","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/2f466add-992b-46c7-a1cc-5c05d59f4bdf?source=cve"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/profile-builder/tags/4.0.3/features/functions.php#L582"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/profile-builder/tags/4.0.3/features/functions.php#L585"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/profile-builder/tags/4.0.3/features/functions.php#L593"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/profile-builder/tags/4.0.3/front-end/default-fields/display-name/display-name.php#L81"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/changeset/3741133/profile-builder"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/changeset/3741133/profile-builder/trunk/features/functions.php"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-16T14:34:33.130780Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-16T14:39:04.655Z","content_hash":"12be8baff789ca25c4a95eca89a4ad8866b6fa12462ec43655c867d5224aa6d6"}}
