GHSA-xmjj-3c76-5w84
HIGHImproper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in directus
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.
directusnpmDescription
Impact
Unauthorized JavaScript can be executed by inserting an iframe into the rich text html interface that links to a file uploaded HTML file that loads another uploaded JS file in its script tag. This satisfies the regular content security policy header, which in turn allows the file to run any arbitrary JS.
Patches
This was resolved in https://github.com/directus/directus/pull/12020 which is released in 9.7.0
Workarounds
You can disable the live embed in the WYSIWYG by adding { "media_live_embeds": false } to the Options Overrides option of the Rich Text HTML interface.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for directus. 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 directus to 9.7.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-xmjj-3c76-5w84 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-xmjj-3c76-5w84 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-xmjj-3c76-5w84. 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-xmjj-3c76-5w84 in your dependencies?
O3 detects GHSA-xmjj-3c76-5w84 across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
