**Name of the Vulnerable Software and Affected Versions**
CSZCMS version 1.3.0
**Description**
A problematic issue has been found, affecting the Site Settings Page component, specifically the /admin/settings/ part of the file. The manipulation of the `Additional Meta Tag` argument with the input `<svg><animate onbegin=alert(1) attributeName=x dur=1s>` leads to cross-site scripting. This issue can be initiated remotely. The exploit has been publicly disclosed.
**Recommendations**
For CSZCMS version 1.3.0, as a temporary workaround, consider restricting access to the `Site Settings Page` component, specifically the `/admin/settings/` endpoint, to minimize the risk of exploitation. Avoid using the `Additional Meta Tag` argument in the affected component until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
