Prior to 0.38.2, the app name validation regex (^[a-z0-9][^/:_A-Z]*$) permits shell metacharacters. When an authenticated user pushes to a git remote with a crafted app name, the name is embedded unquoted into a bash pre-receive hook script via an unquoted heredoc (<<EOF instead of <<'EOF') in fn-git-create-hook() at plugins/git/internal-functions:378. On git push, bash interprets the semicolon as a command separator, executing arbitrary commands as the dokku user"},"products":[{"@id":"cpe:2.3:a:dokku:dokku:\\<_0.38.2:*:*:*:*:*:*:*","identifiers":{"cpe23":"cpe:2.3:a:dokku:dokku:\\<_0.38.2:*:*:*:*:*:*:*"}}],"status":"affected","action_statement":"No fixed version is published yet; monitor the upstream advisory.","timestamp":"2026-06-26T18:41:32.788Z"}]}
