WordPress · Easycart · CVE-2026-4080
**Name of the Vulnerable Software and Affected Versions**
Easy Cart versions prior to 1.9
**Description**
The Easy Cart plugin for WordPress contains a Stored Cross-Site Scripting issue. Authenticated attackers with Contributor-level access or higher can inject arbitrary web scripts into pages. This occurs because the `ectp add to cart()` function fails to properly escape double quote characters when processing shortcode attributes, allowing an attacker to break out of the HTML attribute context and inject event handlers. The affected attributes include `itemid`, `product name`, `product desc`, `product qty`, and `price` within the 'add to cart' shortcode.
**Recommendations**
Update to a version later than 1.8.
As a temporary workaround, restrict the use of the 'add to cart' shortcode and its attributes `itemid`, `product name`, `product desc`, `product qty`, and `price` for users with Contributor-level access.
