{"id":"CVE-2026-93747","published":"2026-09-25T08:16:41.707","lastModified":"2026-09-25T14:17:23.930","description":"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.","cvssScore":6.4,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","cwes":["CWE-79"],"vendors":[],"products":[],"references":[{"url":"https://plugins.trac.wordpress.org/browser/wpforo/tags/3.1.5/classes/Actions.php#L711","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/wpforo/tags/3.1.5/classes/Forms.php#L1074","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/wpforo/tags/3.1.5/classes/Forms.php#L324","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/wpforo/tags/3.1.5/classes/Members.php#L1157","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/wpforo/tags/3.1.5/classes/Members.php#L906","tags":[]},{"url":"https://plugins.trac.wordpress.org/changeset?reponame=&old=3706608%40wpforo&new=3706608%40wpforo","tags":[]},{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/15dc1661-793a-43dd-8a12-8f51da6cb304?source=cve","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
