The Page Builder by SiteOrigin WordPress plugin before 2.38.0 does not sanitize or escape a widget property before storing it and outputting it in the page builder interface, which could allow users with the contributor role and above to perform Stored Cross-Site Scripting attacks against higher-privileged users who open the affected post in the editor.

The Page Builder by SiteOrigin WordPress plugin before 2.38.0 does not restrict the query arguments users can add to its Post Loop widget or limit the loop to posts they are allowed to read, which could allow users with the contributor role and above to read the content of other users' draft, pending, scheduled and private posts and pages.

The SiteOrigin CSS plugin for WordPress is vulnerable to Stored DOM-Based Cross-Site Scripting via the 'url (commentauthorurl)' parameter in all versions up to, and including, 1.6.7 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This is possible because WordPress core's escurl() preserves HTML entity-encoded characters, allowing a crafted entity-encoded payload in the comment 'Website' field to survive storage and be DOM-decoded by the browser into executable markup at the sink.

The SiteOrigin CSS plugin for WordPress is vulnerable to Stored DOM-Based Cross-Site Scripting via the 'href' parameter in all versions up to, and including, 1.6.7 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Successful exploitation requires the malicious comment to be approved and an administrator to subsequently open the Visual Inspector and click the attacker's anchor link, both of which are plausible interactions during routine comment triage.

The SiteOrigin Widgets Bundle plugin for WordPress is vulnerable to Directory Traversal in all versions up to, and including, 1.74.3 via the getinstancecss function. This makes it possible for authenticated attackers, with contributor-level access and above, to read the contents of arbitrary files on the server, which can contain sensitive information. The widget's normal update()/sanitizefieldinput() pipeline — which would reject non-hex color values — is bypassed entirely because the [siteoriginwidget] shortcode handler calls $thewidget->widget() directly on the attacker-supplied decoded JSON instance.

The SiteOrigin Widgets Bundle plugin for WordPress is vulnerable to Local File Inclusion in all versions up to, and including, 1.73.2 via the 'theme' parameter parameter. This makes it possible for authenticated attackers, with contributor-level access and above, to include and execute arbitrary .php 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 .php file types can be uploaded and included. Exploitation requires sending a malicious widgetData payload containing a legacy top-level theme key alongside a non-empty columns array to the /wp-json/sowb/v1/widgets/previews REST endpoint, which bypasses field validation because updatefields() only processes declared form fields.

Editor PHP Object Injection in Page Builder by SiteOrigin <= 2.36.0 versions.

The Page Builder by SiteOrigin plugin for WordPress is vulnerable to Stored Cross-Site Scripting via panelsdata 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 editpost capability checks enforced during save are both satisfied by Contributor-level users for their own posts, and the panelsdata value is stored as post meta — outside the scope of WordPress's unfilteredhtml carve-out — meaning no wpkses fallback prevents the unsanitized WPWidgetCustomHTML content from being persisted and later rendered verbatim on the frontend.

The Vantage theme for WordPress is vulnerable to Stored Cross-Site Scripting via Gallery block text content in versions up to, and including, 1.20.32 due to insufficient output escaping in the gallery template. 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.
