SCA: security update for @haxtheweb/haxcms-nodejs (GHSA-x3x5-7h4h-gwxg)

high Tenable Self-Hosted Container Security Plugin ID 442164

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - HAX CMS helps manage microsite universe with PHP or NodeJs backends. Prior to version 26.0.0, an attack
 chain utilizing Stored XSS alongside dynamic token exposure in the `/system/api/connectionSettings`
 endpoint allows an authenticated attacker to perform a complete cross-tenant account takeover. The API
 dynamically leaks the active session's authentication tokens (including the `jwt`, `user_token`,
 `site_token`, and `appstore_token`) into a global JavaScript variable (`window.appSettings`). An attacker
 can exploit the XSS vulnerability to force a victim's browser to silently fetch their specific connection
 settings, extract the tokens, and exfiltrate them to an attacker-controlled webhook. Version 26.0.0
 patches the issue. (CVE-2026-46511)

Solution

Update the @haxtheweb/haxcms-nodejs library and its related packages to version 26.0.0 or later.
