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 · unedited
HAX CMS helps manage microsite universe with PHP or NodeJs backends. An authenticated Server-Side Request Forgery (SSRF) vulnerability in versions prior to 26.0.0 allows authenticated users to fetch arbitrary internal or local resources and write the responses to a web-accessible directory, enabling arbitrary file read and internal network access. Version 26.0.0 contains a fix.

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 confidence

Authenticated SSRF in HAX CMS allows authenticated users to cause the server to make arbitrary requests to internal/local resources and write the responses to web-accessible directories, enabling arbitrary file read and internal network access.

MitigationUpgrade to version 26.0.0 or later to obtain the fix; if immediate upgrade is not feasible, implement strict validation of user-supplied URLs in authenticated endpoints and restrict network access from the application server to internal resources.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Confirm HAX CMS installation
    Search the web server document root for HAX CMS-specific files, directories, or signature files that indicate HAX CMS is present
    Affected if HAX CMS is found in the environment
  2. Locate version information
    Check for version files, package.json, composer.json, or application configuration that stores the HAX CMS version number
    Affected if Version information cannot be located or is inconsistent across version sources
  3. Compare version to fixed release
    Compare the identified installed version against version 26.0.0 - the version containing the fix
    Affected if Installed version is any version prior to 26.0.0
  4. Verify authenticated access exists
    Confirm that user authentication is enabled and user accounts can access the HAX CMS application
    Affected if Authenticated user accounts can access the application and trigger URL-based features

Environment is affected if HAX CMS is present with a version lower than 26.0.0 and authenticated users can access endpoints capable of making outbound requests to arbitrary URLs

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.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade to version 26.0.0 or later to obtain the fix; if immediate upgrade is not feasible, implement strict validation of user-supplied URLs in authenticated endpoints and restrict network access from the application server to internal resources.

Recommended fix High confidence

26.0.0

  1. 1. Back up your current HAX CMS installation including database and all configuration files
  2. 2. Download HAX CMS version 26.0.0 from the official GitHub repository (github.com)
  3. 3. Review the upgrade instructions provided in the release notes or documentation
  4. 4. Replace the existing installation files with the new version 26.0.0 files
  5. 5. Run any database migration scripts if required by the upgrade
  6. 6. Verify the installation was successful by logging in and testing core functionality
  7. 7. Confirm the SSRF vulnerability is remediated by verifying that internal/local resource fetching is no longer possible
Caveat Review release notes for potential breaking changes between your current version and 26.0.0, as major version upgrades may include API or configuration changes
