GHSA-54vw-f4xf-f92j
MEDIUMHAX CMS application pages vulnerable to clickjacking
EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
Blast Radius
Weekly download volume for affected packages — a proxy for how broadly this vulnerability is deployed.
@haxtheweb/haxcms-nodejsnpmDescription
Summary
All pages within the HAX CMS application do not contain headers to stop other websites from loading the site within an iframe. This applies to both the CMS and generated sites.
PoC
To replicate this vulnerability, load the target page in an iframe and observe the rendered content.
Impact
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.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for @haxtheweb/haxcms-nodejs. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
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.
How O3 protects you
O3 pinpoints whether GHSA-54vw-f4xf-f92j is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-54vw-f4xf-f92j. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-54vw-f4xf-f92j in your dependencies?
O3 detects GHSA-54vw-f4xf-f92j across npm, Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
