CVE-2026-82870
CRITICALCVE-2026-82870 is a critical-severity (CVSS 9.6) CWE-639 vulnerability. O3 Security confirms whether CVE-2026-82870 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Description
ToolJet before v3.16.208 fails to validate organizationId ownership in database write and destroy routes, allowing any builder-role user to create, alter, or drop tables in other organizations' databases. Attackers can exploit missing organization-resolving guards to permanently delete tables, insert arbitrary data, and modify schemas across tenant boundaries on shared instances.
Detection & mitigation playbook
VulnerabilityDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for the affected component. 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.
Remediation status
No patched version of the affected component has shipped for CVE-2026-82870 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
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-2026-82870 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-2026-82870. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
