- CVE-2026-13295, 27 Jun 2026
- The Page Builder by SiteOrigin plugin for WordPress is vulnerable to Stored Cross-Site Scripting via panels_data Parameter in all versions up to, and including, 2.34.3 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. This is possible because the nonce and edit_post capability checks enforced during save are both satisfied by Contributor-level users for their own posts, and the panels_data value is stored as post meta - outside the scope of WordPress's unfiltered_html carve-out - meaning no wp_kses fallback prevents the unsanitized WP_Widget_Custom_HTML content from being persisted and later rendered verbatim on the frontend. CVE record
- CVE-2026-2448, 3 Mar 2026
- The Page Builder by SiteOrigin plugin for WordPress is vulnerable to Local File Inclusion in all versions up to, and including, 2.33.5 via the locate_template() function. This makes it possible for authenticated attackers, with Contributor-level access and above, to include and execute arbitrary files on the server, allowing the execution of any PHP code in those files. This can be used to bypass access controls, obtain sensitive data, or achieve code execution in cases where images and other “safe” file types can be uploaded and included. CVE record

- The Page Builder by SiteOrigin plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Embedded Video(PB) widget in all versions up to, and including, 2.31.4 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. CVE record
