CVE-2026-13295
CVSS v3.1
6.4
Medium
| Vector | AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N |
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.
