Security readout for executives and security teams
Plain-English summary
HAX CMS versions 11.0.6 through before 25.0.0 have a stored cross-site scripting flaw. An authenticated low-privilege user could store malicious content that runs when another user interacts with it, potentially leading to account takeover. The vendor states the issue is patched in version 25.0.0.
Executive priority
Treat this as a high-priority patch for internet-accessible or multi-user HAX CMS environments. The main business risk is account takeover through trusted user interaction. Prioritize systems where many users can edit content or where administrators regularly review user-created content.
Technical view
CVE-2026-22704 is CWE-79 stored XSS in HAX CMS. The CVSS 3.1 score is 8.1 with network attack vector, low privileges required, user interaction required, high complexity, and changed scope. Impact is rated high for confidentiality, integrity, and availability. A fix is associated with HAX CMS Node.js v25.0.0.
Likely exposure
Organizations running HAX CMS versions >= 11.0.6 and < 25.0.0 are potentially exposed, especially where untrusted or lower-privileged users can create or edit site content. The provided data does not identify affected PHP versus Node.js deployments beyond HAX CMS generally and the referenced Node.js patch/release.
Exploitation context
The sources do not indicate known active exploitation, and the CVE is not listed as KEV in the provided bundle. Exploitation requires an authenticated low-privilege attacker and user interaction, but successful exploitation may result in account takeover.
Researcher notes
The public bundle identifies stored XSS with account takeover potential but does not provide detailed exploit mechanics. Product naming in the affected metadata appears inconsistent, listing vendor haxtheweb and product issues while the description names HAX CMS. Validate against the GitHub advisory, commit, and v25.0.0 release.
Mitigation direction
- Upgrade affected HAX CMS deployments to version 25.0.0 or later.
- Review the GitHub security advisory for vendor-specific guidance.
- Restrict content editing privileges until affected systems are upgraded.
- Check vendor release notes before applying changes in production.
Validation and detection
- Inventory HAX CMS deployments and record installed versions.
- Confirm no deployment remains on versions 11.0.6 through 24.x.
- Verify the 25.0.0 release or later is installed after remediation.
- Review user roles with content editing permissions on affected sites.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
