Gila · Gila Cms · CVE-2019-20803
**Name of the Vulnerable Software and Affected Versions**
Gila CMS versions prior to 1.11.6
**Description**
The issue is related to reflected XSS, which occurs via the `id` parameter in the `admin/content/postcategory` endpoint. This parameter is mishandled when `g preview theme` is used.
**Recommendations**
For versions prior to 1.11.6, update to version 1.11.6 or later to resolve the issue. As a temporary workaround, consider restricting access to the `admin/content/postcategory` endpoint until the update is applied. Avoid using the `id` parameter in this endpoint until the issue is resolved.
