Simplcommerce · Simplcommerce · CVE-2026-11975
**Name of the Vulnerable Software and Affected Versions**
SimplCommerce versions prior to commit 6142d3b5
**Description**
Stored cross-site scripting (XSS) exists in the 'NewsItemApiController' endpoint. An authenticated administrator can execute arbitrary JavaScript through the `ShortContent` and `FullContent` fields. This occurs because the input is stored without HTML sanitization and is subsequently rendered unencoded using the `@Html.Raw()` function.
**Recommendations**
Update SimplCommerce to commit 6142d3b5 or a later version.
As a temporary mitigation, restrict administrative access to the news item management features.
