CVE-2026-45661: Dokploy: Remote Code Execution through Path Traversal
Dokploy is a free, self-hostable Platform as a Service (PaaS). In 0.26.5 and earlier, a critical path traversal vulnerability exists in Dokploy v0.26.5 that allows authenticated users to write arbitrary files to the filesystem during application deployment. When combined with Dokploy's remote server deployment feature, this vulnerability enables arbitrary file write to remote server filesystems, automatic remote code execution via cron jobs, complete server compromise, data exfiltration without user interaction, and persistent backdoor installation. This vulnerability bypasses all container isolation on remote server deployments.
Security readout for executives and security teams
Plain-English summary
Dokploy versions 0.26.5 and earlier allow an authenticated user to write files outside intended paths during deployment. On remote server deployments, that can become full server compromise, including remote code execution, data theft, and persistence. The source does not show active exploitation, but the impact is severe.
Executive priority
Treat this as urgent for any Dokploy-backed production or shared environment. A low-privileged authenticated deployment user may be enough to compromise remote servers, so containment and vendor-guided remediation should happen quickly.
Technical view
The issue is a path traversal/arbitrary file write flaw during application deployment in Dokploy <=0.26.5. With the remote server deployment feature, arbitrary writes can reach remote server filesystems and bypass container isolation, enabling code execution through existing scheduled execution paths and broader compromise.
Likely exposure
Self-hosted Dokploy installations running 0.26.5 or earlier are potentially exposed. Risk is highest where authenticated users can deploy applications, and where Dokploy is configured to deploy to remote servers.
Exploitation context
The source states exploitation requires authenticated access and no user interaction. CISA KEV status is false in the provided bundle, and no cited source confirms active exploitation in the wild.
Researcher notes
Evidence is limited to the CVE bundle and Dokploy GitHub advisory reference. The bundle does not name a fixed release or concrete mitigation. Avoid assuming exploit availability; focus validation on version, authenticated deployment access, and remote server deployment usage.
Mitigation direction
Check the Dokploy advisory for fixed versions or official mitigation guidance.
Restrict Dokploy access to trusted authenticated users only.
Disable or limit remote server deployments until vendor guidance is applied.
Audit Dokploy deployments and remote hosts for unexpected file changes.
Review scheduled tasks and persistence locations for unauthorized changes.
Validation and detection
Inventory all Dokploy instances and record deployed versions.
Flag any instance running Dokploy 0.26.5 or earlier.
Confirm whether remote server deployment is enabled or used.
Review deployment history for unexpected authenticated activity.
Inspect affected remote servers for suspicious scheduled tasks or files.
