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."}],"title":"wpForo Forum <= 3.1.6 - Authenticated (Subscriber+) Stored Cross-Site Scripting via 'telegram' Profile Field","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/15dc1661-793a-43dd-8a12-8f51da6cb304?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/wpforo/tags/3.1.5/classes/Forms.php#L324"},{"url":"https://plugins.trac.wordpress.org/browser/wpforo/tags/3.1.5/classes/Forms.php#L1074"},{"url":"https://plugins.trac.wordpress.org/browser/wpforo/tags/3.1.5/classes/Members.php#L1157"},{"url":"https://plugins.trac.wordpress.org/browser/wpforo/tags/3.1.5/classes/Members.php#L906"},{"url":"https://plugins.trac.wordpress.org/browser/wpforo/tags/3.1.5/classes/Actions.php#L711"},{"url":"https://plugins.trac.wordpress.org/changeset?reponame=&old=3706608%40wpforo&new=3706608%40wpforo"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')","cweId":"CWE-79","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","baseScore":6.4,"baseSeverity":"MEDIUM"}}],"credits":[{"lang":"en","type":"finder","value":"Ivaylo"}],"timeline":[{"time":"2026-09-18T16:25:47.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-09-24T19:09:27.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2026-93747","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2026-09-25T12:52:02.638885Z"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-09-25T13:00:15.892Z"}}]}}
