CVE-2026-35442
HIGHCVE-2026-35442 is a high-severity (CVSS 8.1) Information Exposure vulnerability in directus. O3 Security confirms whether CVE-2026-35442 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Directus: Authenticated Users Can Extract Concealed Fields via Aggregate Queries
Real-World Exposure
How broadly this vulnerability is actually deployed: weekly install volume shows current usage, a proxy for how much of the ecosystem is exposed.
directusnpmDescription
Directus is a real-time API and App dashboard for managing SQL database content. Prior to 11.17.0, 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. This vulnerability is fixed in 11.17.0.
Affected Packages

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 11.17.0 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 pinpoints whether CVE-2026-35442 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 CVE-2026-35442. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
