{"schema":"threatline.record/2","record":{"id":"CVE-2026-93656","aliases":[],"summary":"User Profile Builder <= 4.0.2 - Authenticated (Subscriber+) Stored Cross-Site Scripting via Avatar Field","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 Avatar Field in all versions up to, and including, 4.0.2 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. This is exploitable via a nonce-free GET request to /wp-admin/profile.php, requiring no profile-form submission; a Subscriber can plant the malicious attachment URL, which then executes when an administrator opens that user's Edit User screen.","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-2026-93656","source_modified_at":"2026-09-25T13:00:15.505Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"User Profile Builder – Beautiful User Registration Forms, User Profiles & User Role Editor","vendor":"cozmoslabs","versions":[{"version":"0","status":"affected","lessThanOrEqual":"4.0.2","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":6.4,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00201,"percentile":0.0948,"score_date":"2026-10-23"},"published_at":"2026-09-25T07:40:26.659Z","modified_at":"2026-09-25T13:00:15.505Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-93656","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-25T13:00:15.505Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-93656","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/4d4991ff-903a-410a-b472-1a5f76a32940?source=cve"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/profile-builder/tags/4.0.2/front-end/default-fields/upload/upload_helper_functions.php#L286"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/profile-builder/tags/4.0.2/front-end/default-fields/avatar/avatar.php#L43"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/profile-builder/tags/4.0.2/front-end/default-fields/avatar/avatar.php#L67"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/profile-builder/tags/4.0.2/front-end/default-fields/avatar/avatar.php#L75"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/profile-builder/tags/4.0.2/front-end/default-fields/fields-functions.php#L30"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/changeset/3708665/profile-builder"}],"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":"2026-09-25T12:51:16.336339Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-09-25T13:00:15.505Z","content_hash":"e456797ab4e4f79d860c95edc5cdc4219933b0a687ca989328c17644f2b5e6f0"}}
