Detailsinfo

A vulnerability classified as critical has been found in dokploy up to 0.26.5. This affects some unknown processing. The manipulation with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

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.

The advisory is shared at github.com. This vulnerability is uniquely identified as CVE-2026-45661 since 05/12/2026. The exploitability is told to be easy. It is possible to initiate the attack remotely. Neither technical details nor an exploit are publicly available.
