## What is CVE-2025-54127?

CVE-2025-54127 is a critical vulnerability in haxtheweb issues, published on 21 Jul 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

HAXcms with nodejs backend allows users to start the server in any HAXsite or HAXcms instance. In versions 11.0.6 and below, the NodeJS version of HAXcms uses an insecure default configuration designed for local development. The default configuration does not perform authorization or authentication checks. If a user were to deploy haxcms-nodejs without modifying the default settings, ‘HAXCMS_DISABLE_JWT_CHECKS‘ would be set to ‘true‘ and their deployment would lack session authentication. This is fixed in version 11.0.7.

Weakness: CWE-1188 (Initialization of a Resource with an Insecure Default)
