The Stackable – Page Builder Gutenberg Blocks plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'title' parameter of the Button block in all versions up to, and including, 3.13.11 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The iframe-font-preview.php file of the titan-framework does not properly escape the font-weight and font-family GET parameters before outputting them back in an href attribute, leading to Reflected Cross-Site Scripting issues

Multiple cross-site scripting (XSS) vulnerabilities in Gambit Design Bandwidth Meter, 0.72 and possibly 1.2, allow remote attackers to inject arbitrary web script or HTML via the PATH_INFO to (1) view_by_name.php or (2) view_by_ip.php in admin/. NOTE: some sources report that the affected product is ShaPlus Bandwidth Meter, but this is incorrect.
