Stored XSS in bbPress Style Pack WordPress Plugin

Publication date: 2026-10-01

Last updated on: 2026-10-01

Assigner: Wordfence

Description
The bbp style pack plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'display_name (via /wp-admin/profile.php) + bbp_reply_content (via bbPress reply form)' parameter in all versions up to, and including, 6.4.8 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. Successful exploitation requires the attacker to wrap their crafted reply in a <pre> block, which prevents WordPress's wpautop/wptexturize processors from converting straight double quotes in the stored display name into typographic curly-quote entities that would otherwise neutralize the attribute-injection.

Executive Summary

This is a Stored Cross-Site Scripting (XSS) vulnerability in the bbp style pack plugin for WordPress. It allows authenticated attackers with subscriber-level access or higher to inject malicious scripts into web pages by exploiting insufficient input sanitization and output escaping in the display_name and bbp_reply_content parameters. The attack requires wrapping the crafted reply in a <pre> block to bypass WordPress's text processors.

Detection Guidance

Check WordPress sites using the bbp style pack plugin version 6.4.8 or lower. Inspect user profiles and bbPress reply forms for stored scripts. Look for unusual content in display_name or bbp_reply_content fields.

Impact Analysis

An attacker could steal user sessions, deface websites, or redirect users to malicious sites. Since the injected scripts execute when users access affected pages, it poses risks to user data and website integrity. The impact depends on the attacker's goals and the site's user base.

Compliance Impact

This vulnerability could lead to unauthorized access to user data, violating GDPR's data protection principles or HIPAA's security requirements for protected health information. Non-compliance may result in legal penalties, reputational damage, and loss of trust.

Mitigation Strategies

Update the bbp style pack plugin to the latest version. Remove suspicious scripts from user profiles and replies. Implement input sanitization for display_name and bbp_reply_content fields.
