{"schema":"threatline.record/2","record":{"id":"CVE-2026-93747","aliases":[],"summary":"wpForo Forum <= 3.1.6 - Authenticated (Subscriber+) Stored Cross-Site Scripting via 'telegram' Profile Field","details":"The wpForo Forum plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'telegram' profile field in versions up to, and including, 3.1.6. This is due to insufficient input sanitization and output escaping in the profile_update action — the raw $_POST['data'] array is copied into a $custom_fields variable before validate() and sanitize() run, both of which operate only on a parallel $user reference, leaving $custom_fields unsanitized when it is persisted via update_custom_fields(); on render, wpforo_decode() reverses the entity encoding and the value is echoed without escaping in field_wrap_profile(). 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.","categories":["Unclassified"],"product":"wpForo Forum","vendor":"tomdever","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-93747","source_modified_at":"2026-09-25T13:00:15.892Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"wpForo Forum","vendor":"tomdever","versions":[{"version":"0","status":"affected","lessThanOrEqual":"3.1.6","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":6.4,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00201,"percentile":0.09482,"score_date":"2026-10-23"},"published_at":"2026-09-25T07:40:24.854Z","modified_at":"2026-09-25T13:00:15.892Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-93747","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-25T13:00:15.892Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-93747","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/15dc1661-793a-43dd-8a12-8f51da6cb304?source=cve"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/wpforo/tags/3.1.5/classes/Forms.php#L324"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/wpforo/tags/3.1.5/classes/Forms.php#L1074"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/wpforo/tags/3.1.5/classes/Members.php#L1157"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/wpforo/tags/3.1.5/classes/Members.php#L906"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/wpforo/tags/3.1.5/classes/Actions.php#L711"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/changeset?reponame=&old=3706608%40wpforo&new=3706608%40wpforo"}],"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":"2026-09-25T12:52:02.638885Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-09-25T13:00:15.892Z","content_hash":"73c553170da39afa868d75364388b0d92c8e347a5c22f04111b0c179610369e0"}}
