Description
BuddyPress 14.4.0 contains a regular expression injection vulnerability in the activity mention resolver that, when username compatibility mode is enabled, allows attackers to manipulate a REGEXP database clause by crafting mention names containing regex metacharacters. Attackers can submit @mentions whose metacharacters pass through esc_sql unescaped and are inserted into an unprepared REGEXP query against the users table, enabling boolean-based inference of usernames and denial of service through catastrophic backtracking.
<p>Are you looking for modern, robust, and sophisticated social network software? BuddyPress is a suite of components that are common to a typical social network, and allows for great add-on features through WordPress’s extensive plugin system.</p>
<p>Aimed at site builders & developers, BuddyPress is focused on ease of integration, ease of use, and extensibility. It is deliberately powerful yet unbelievably simple social network software, built by contributors to WordPress.</p>

<p>Members can register on your site to create user profiles, have private conversations, make social connections, create and interact in groups, and much more. Truly a social network in a box, BuddyPress helps you build a home for your company, school, sports team, or other niche community.</p>
<h4>Built with developers in mind</h4>
<p>BuddyPress helps site builders & developers add community features to their websites. It comes with a robust theme compatibility API that does its best to make every BuddyPress content page look and feel right with just about any WordPress theme. You will likely need to adjust some styling on your own to make everything look pristine.</p>
<p>BuddyPress themes are just WordPress themes with additional templates, and with a little work, you could easily create your own, too! A handful of BuddyPress-specific themes are readily available for download from WordPress.org, and lots more are available from third-party theme authors.</p>
<p>BuddyPress also comes with built-in support for Akismet and <a href="https://wordpress.org/plugins/bbpress/" rel="ugc">bbPress</a>, two very popular and very powerful WordPress plugins. If you’re using either, visit their settings pages and ensure everything is configured to your liking.</p>
<h4>The BuddyPress Add-ons</h4>
<p>WordPress.org is home to some amazing Add-ons for BuddyPress, including:</p>

</ul>
<p><strong>NB</strong>: BP Classic is a backwards compatibility Add-on for BuddyPress 12.0 and up bringing back the BP Legacy URL parser, the BP Default theme and BP Legacy widgets.</p>
