CVE-2026-93747 Details
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.
A stored cross-site scripting vulnerability has been identified in the wpForo Forum plugin for WordPress, affecting versions through 3.1.6. The issue arises from inadequate input sanitization and output escaping in the profile_update action. Specifically, the raw data from the 'telegram' profile field is transferred to a custom_fields variable before any validation or sanitization occurs. This unsanitized data is then saved and later rendered on the page, where it can execute injected scripts. This vulnerability allows authenticated attackers with subscriber-level access or higher to inject malicious scripts that run when a user views the affected page.
Users are advised to update the wpForo Forum plugin to version 3.1.7 or a newer patched version.
