@haxtheweb/haxcms-nodejsnpmDescription
HAX CMS allows users to manage their microsite universe with a NodeJS or PHP backend. In haxcms-nodejs versions 11.0.12 and below and in haxcms-php versions 11.0.7 and below, all pages within the HAX CMS application do not contain headers to prevent other websites from loading the site within an iframe. This applies to both the CMS and generated sites. An unauthenticated attacker can load the standalone login page or other sensitive functionality within an iframe, performing a UI redressing attack (clickjacking). This can be used to perform social engineering attacks to attempt to coerce users into performing unintended actions within the HAX CMS application. This is fixed in haxcms-nodejs version 11.0.13 and haxcms-php 11.0.8.

Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for @haxtheweb/haxcms-nodejs, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update @haxtheweb/haxcms-nodejs to 11.0.13 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-54vw-f4xf-f92j is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
