CVE-2026-44366
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedVvveb is a powerful and easy to use CMS with page builder to build websites, blogs or ecommerce stores. Prior to 1.0.8.1, a Stored Cross-Site Scripting (XSS) vulnerability exists in the Vvveb CMS comment submission flow. The author field is submitted by an unauthenticated user on any public post page, stored without sanitization, and later rendered unsanitized in two distinct sinks: This vulnerability is fixed in 1.0.8.1.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceA stored Cross-Site Scripting (XSS) vulnerability in Vvveb CMS allows unauthenticated users to inject malicious JavaScript via the comment submission author field. The author input is stored without sanitization and rendered unsanitized in two display locations within the application.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm Vvveb CMS is installedIdentify if the web application uses Vvveb CMS by checking for Vvveb-specific files, login pages, or footer branding. Common locations include the root directory for index.php or admin login pages.Affected if The target is running Vvveb CMS
-
Determine the installed versionCheck the version number of Vvveb CMS, typically found in a version file, changelog, or within the admin dashboard under system information or about section.Affected if The installed version is earlier than 1.0.8.1 (e.g., 1.0.8, 1.0.7, or older)
-
Verify comment functionality is enabledConfirm the comment/submission feature is active on the site by navigating to pages that accept comments or checking the admin panel for comment module settings.Affected if Comments module is enabled and accessible to unauthenticated users
-
Test the author field for XSS vulnerabilitySubmit a comment with a benign XSS payload (such as <script>alert(1)</script> or <img src=x onerror=alert(1)>) in the author/name field, then view the comment in both display locations to verify the script executes.Affected if The injected script executes without sanitization in either display location, confirming stored XSS
A user is affected if they are running Vvveb CMS version earlier than 1.0.8.1 with the comment feature enabled and the author field renders unescaped HTML/JavaScript.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedUpgrade to Vvveb CMS version 1.0.8.1 or later, which implements proper input sanitization for the comment author field.
1.0.8.1
- 1. Identify current Vvveb CMS version by checking the admin dashboard or version file
- 2. Create a complete backup of the database and all website files
- 3. Download Vvveb version 1.0.8.1 from the official repository or source
- 4. Extract and replace CMS files with the new version, preserving configuration files
- 5. Run any available database migration scripts included in the update
- 6. Verify the upgrade was successful by checking the admin panel shows version 1.0.8.1
- 7. Test the comment submission form to confirm the XSS vulnerability is remediated
