GHSA-59g8-h59f-8hjp

### Summary The NodeJS version of HAX CMS has a disabled Content Security Policy (CSP). This configuration is insecure for a production application because it does not protect against cross-site-scripting attacks.

### Details The `contentSecurityPolicy` value is explicitly disabled in the application's Helmet configuration in `app.js`.


#### Affected Resources - [app.js:52](https://github.com/haxtheweb/haxcms-nodejs/blob/b1f95880b42fea6ed07855b5804b29b182ec5e07/src/app.js#L52)

### PoC To reproduce this vulnerability, [install](https://github.com/haxtheweb/haxcms-nodejs) HAX CMS NodeJS. The application will load without a CSP configured.

### Impact In conjunction with an XSS vulnerability, an attacker could execute arbitrary scripts and exfiltrate data, including session tokens and sensitive local data.
