MEDIUMURL Redirection to Untrusted Site in OAuth2/OpenID 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.

directusnpmDescription
Summary
The authentication API has a redirect parameter that can be exploited as an open redirect vulnerability as the user tries to log in via the API URL https://docs.directus.io/reference/authentication.html#login-using-sso-providers /auth/login/google?redirect for example.
Details
There's a redirect that is done after successful login via the Auth API GET request to directus/auth/login/google?redirect=http://malicious-fishing-site.com, which I think is here: https://github.com/directus/directus/blob/main/api/src/auth/drivers/oauth2.ts#L394. While credentials don't seem to be passed to the attacker site, the user can be phished into clicking a legitimate directus site and be taken to a malicious site made to look like a an error message "Your password needs to be updated" to phish out the current password.
PoC
Turn on any auth provider in Directus instance. Form a link to directus-instance/auth/login/:provider_id?redirect=http://malicious-fishing-site.com, login and get taken to malicious-site. Tested on the ory OAuth2 integration.
Impact
Users who login via OAuth2 into Directus.

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 10.10.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-fr3w-2p22-6w7p 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-fr3w-2p22-6w7p 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-fr3w-2p22-6w7p. 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-fr3w-2p22-6w7p in your dependencies?
O3 detects GHSA-fr3w-2p22-6w7p across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
