Exploitation Status
Proof-of-concept exploit code exists
- CISA’s SSVC triage found public proof-of-concept exploit code for this CVE, though no confirmed active exploitation.
- A successful exploit gives an attacker total control of the affected component, not partial access.

Description
Dokploy is a free, self-hostable Platform as a Service (PaaS). Prior to 0.29.13, the WebSocket handler in apps/dokploy/server/wss/terminal.ts validates a session but does not authorize access to the requested server. An authenticated user can connect to /terminal?serverId=local, select the special serverId=local branch, and obtain an interactive terminal on the Dokploy host without an organization role or server-access check. This issue is fixed in version 0.29.13.
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-2026-72866 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-2026-72866 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-2026-72866. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
