GHSA-g27j-74fp-xfpr is a critical-severity (CVSS 9.8) CWE-942 vulnerability in directus. A fix is available for directus — see the affected versions and patch details below.
Insecure default value for CORS configuration
Exploitation Status
No confirmed exploitation observed yet
- CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.
- A successful exploit gives an attacker total control of the affected component, not partial access.
- CISA’s own triage has not observed active exploitation or public proof-of-concept code for this CVE as of its last assessment.

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.
How urgent is this, really
GHSA-g27j-74fp-xfpr plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.
Where this sits among everything scored
Of 377,166 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.
Real-World Exposure
How broadly this vulnerability is actually deployed: weekly install volume shows current usage, and reverse-dependency count shows how many other packages break if it stays unpatched.
directusnpmDescription
Impact
The default value for the CORS_ENABLED and CORS_ORIGIN configuration was set to be very permissive by default. This could lead to unauthorized access in uncontrolled environments when the configuration hasn't been changed.
Patches
The default values for CORS have been changed in https://github.com/directus/directus/pull/12022 which is released under 9.7.0
Workarounds
Configure the CORS environment variables to match your project's usage, rather than leaving them at the (permissive) defaults.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for directus, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update directus to 9.7.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-g27j-74fp-xfpr 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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-g27j-74fp-xfpr can be triaged on real exposure rather than presence alone.
Tailored to GHSA-g27j-74fp-xfpr. 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-g27j-74fp-xfpr in your dependencies?
O3 Security finds GHSA-g27j-74fp-xfpr across npm dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
