As published by the source; long descriptions are shortened.

Impact NukeViet CMS <= 4.5.08 contains a Stored Cross-Site Scripting (XSS) vulnerability caused by insufficient server-side input sanitization in the Request class. The application relies primarily on client-side filtering to sanitize HTML tags and attributes in user-submitted content, which can be bypassed by intercepting and modifying HTTP requests directly (e.g., using Burp Suite). This affects any module or functionality that accepts user HTML input through the Request class. An attacker can inject malicious payloads such as <iframe srcdoc="&lt;img src=1 onerror=alert(document.cookie)&gt;"</iframe, which are stored server-side and executed in the browser of any user who views the content. Who is impacted: - Administrators and moderators who view user-submitted content (e.g., contact messages, comments, or any module using the Request class for HTML input). - The Contact module was used as a proof of concept, but the vulnerability is not limited to this module. - No authentication…

# Patch Next advisory brief: CVE-2026-41147

Advisory: NukeViet CMS: Stored Cross-Site Scripting (XSS) via insufficient server-side input sanitization in Request class
IDs: CVE-2026-41147, GHSA-64rr-pp78-62ww
Record: https://patchnext.com/advisories/cve-2026-41147 (revision 1, source checked 26 Oct 2026, 14:48 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.7)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor response not established. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist nukeviet/nukeviet: affected <= 4.4.01

## Suggested inspection (read-only)
- Packagist nukeviet/nukeviet: check the installed version with your package manager.

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on nukeviet/nukeviet.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
