Dokku - Dokku - CRITICAL - CVE-2026-45408. Dokku, a docker-powered Platform as a Service (PaaS), contains a vulnerability in its app name validation regex before version 0.38.2, allowing the inclusion of shell metacharacters. When an authenticated user pushes a crafted app name to a git remote, it is embedded unquoted in a bash pre-receive hook script. This exploitation leads to bash interpreting the semicolon as a command separator, enabling the execution of arbitrary commands with the privileges of the dokku user, potentially compromising the deployment.
