Exploitation Status
No confirmed exploitation observed yet
- 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
CVE-2026-35442 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 377,636 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
Summary
Aggregate functions (min, max) applied to fields with the conceal special type incorrectly return raw database values instead of the masked placeholder. When combined with groupBy, any authenticated user with read access to the affected collection can extract concealed field values, including static API tokens and two-factor authentication secrets from directus_users.
Details
Fields marked with conceal are protected by payload processing logic that replaces real values with a masked placeholder on read. This protection works correctly for standard item queries, but aggregate query results are structured differently, operations are nested under their function name rather than appearing as flat field keys. The masking logic does not account for this nested structure, causing it to silently skip concealed fields in aggregate responses and return their raw values to the client.
Impact
-
Account Takeover An authenticated attacker can harvest static API tokens for all users, including administrators, enabling immediate authentication as any account without credentials.
-
2FA Bypass TOTP seeds stored in directus_users can similarly be extracted, allowing an attacker to bypass two-factor authentication for any account.

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 11.17.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-35442 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-2026-35442 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2026-35442. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
