Directus missing permission checks for manual trigger Flows
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.
- 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
CVE-2025-53889 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
Directus is a real-time API and App dashboard for managing SQL database content. Starting in version 9.12.0 and prior to version 11.9.0, Directus Flows with a manual trigger are not validating whether the user triggering the Flow has permissions to the items provided as payload to the Flow. Depending on what the Flow is set up to do this can lead to the Flow executing potential tasks on the attacker's behalf without authenticating. Bad actors could execute the manual trigger Flows without authentication, or access rights to the said collection(s) or item(s). Users with manual trigger Flows configured are impacted as these endpoints do not currently validate if the user has read access to directus_flows or to the relevant collection/items. The manual trigger Flows should have tighter security requirements as compared to webhook Flows where users are expected to perform do their own checks. Version 11.9.0 fixes the issue. As a workaround, implement permission checks for read access to Flows and read access to relevant collection/items.

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 11.9.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-53889 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 CVE-2025-53889 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2025-53889. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
