Description¶

Dokploy is a free, self-hostable Platform as a Service (PaaS). From 0.29.3 until 0.29.13, the incomplete fix for CVE-2026-45628 leaves packages/server/src/db/schema/compose.ts branch fields without server-side validation, allowing a direct compose.update request to store a malicious customGitBranch, branch, gitlabBranch, bitbucketBranch, or giteaBranch. A low-privileged authenticated user can trigger compose.deploy, which passes the stored branch to shell-based Git clone commands in packages/server/src/utils/providers/git.ts, github.ts, gitlab.ts, bitbucket.ts, and gitea.ts, resulting in arbitrary host command execution. This issue is fixed in version 0.29.13.
