CVE-2026-2448
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe 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.

dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify Page Builder by SiteOrigin plugin is installedNavigate to WordPress Admin > Plugins and locate 'Page Builder by SiteOrigin' in the list of installed plugins, or inspect the plugin directory at /wp-content/plugins/siteorigin-panels/Affected if The plugin is present in the installation
-
Determine installed plugin versionIn WordPress Admin > Plugins, click on the plugin to view its details and note the version number displayed, or read the 'Version:' field from the plugin's main PHP file header at /wp-content/plugins/siteorigin-panels/siteorigin-panels.phpAffected if The installed version is 2.33.5 or earlier (the vulnerability was fixed in versions newer than 2.33.5)
-
Confirm plugin is activeIn WordPress Admin > Plugins, verify that Page Builder by SiteOrigin shows as 'Active' rather than 'Inactive' or 'Network Active'Affected if The plugin is active and the vulnerable version is installed
-
Identify users with Contributor-level access or higherIn WordPress Admin > Users, review the role column for each user account to identify any users assigned the Contributor role, Author role, Editor role, or Administrator role. Alternatively, query the wp_usermeta table for entries where meta_key equals 'wp_capabilities' and meta_value contains 'contributor', 'author', 'editor', or 'administrator'Affected if At least one user account with Contributor-level access or higher exists on the site
-
Check for custom template files that could be includedExamine the /wp-content/themes/ directory and any custom theme files for includes or require statements that leverage the plugin's locate_template() function. Also review the plugin's template loading behavior in the siteorigin-panels.php file for vulnerable include patternsAffected if Custom template files exist and the vulnerable locate_template() function is in use with user-controllable input
You are affected if the Page Builder by SiteOrigin plugin is installed, active, and running version 2.33.5 or earlier while having at least one user with Contributor-level access or higher.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpdate the Page Builder by SiteOrigin plugin to a version newer than 2.33.5. Additionally, restrict file upload capabilities and review user role permissions to limit contributor-level access until the patch is applied.
