eCommerce Product Catalog permits Contributor-level stored cross-site scripting
eCommerce Product Catalog through 3.5.10 lets a Contributor or higher store script-capable input in the style shortcode attribute. The value survives save-time wp_kses_post processing inside shortcode brackets and becomes tainted HTML only when the shortcode handler renders the page.

This CVE was published Aug 25, 2026 and is one of 15 known issues for this plugin.
Update, patch or deactivate.
Update to 3.5.11 or later, remove untrusted style shortcode values, and invalidate privileged sessions if malicious content was viewed.
A safe version is available, so updating to that version or later is the preferred remediation. If an immediate update is not practical, consider a targeted application patch or temporarily restricting the affected functionality.
Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.
Technical description
The eCommerce Product Catalog plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'style' Shortcode Attribute in all versions up to, and including, 3.5.10 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. The payload bypasses WordPress's save-time wp_kses_post sanitization because the malicious content is stored inside shortcode brackets with no HTML tags; the tainted HTML output is only generated at render time by the shortcode handler.
