- Severity: CVSS 7.2 (High), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N
- CISA SSVC: exploitation=none, automatable=yes, technicalImpact=partial

- Published: 2026-10-09 · Updated: 2026-10-09

## Affected

- OceanWP Ocean Pro Demos: through 1.5.4
- OceanWP Ocean eComm Treasure Box: through 1.8.0

## Description

The Ocean Pro Demos and Ocean eComm Treasure Box plugins for WordPress is vulnerable to Stored Cross-Site Scripting via the 'content' parameter in all versions up to, and including, 1.5.4, and 1.8.0, respectively, due to insufficient authorization, input sanitization, and output escaping in the Popup Builder's save_popup_content AJAX action. This makes it possible for unauthenticated attackers to inject arbitrary web scripts into a published Gutenberg popup that will execute whenever a user accesses a page on which the popup is configured to display. A valid premium license, the Popup Builder module, and at least one published Gutenberg popup configured for display are required.
