CVE-2026-73040
HighCVSS 8.8Exploitation Probability (EPSS)
Elevated risk60th percentile - higher than 60% of all known CVEs
Summary
Dockge validates a stack name only on the write path, allowing an authenticated user to use traversal sequences in the name to access directories outside the managed stacks directory. This can disclose .env or Compose files and delete directories containing a valid Compose file. With disableAuth enabled, these operations are available without authentication.
Risk Assessment
Exposure of secrets from .env or Compose files of other host applications and potential deletion of directories, leading to serious security breaches and data loss.
Recommendation
Upgrade Dockge to a patched version or apply a workaround by restricting access to Dockge and avoiding the disableAuth configuration.

Original NVD description (English source)
Dockge validates a stack name only on the write path. In backend/stack.ts the allow-list check in validate(), which requires the name to match ^[a-z0-9_-]+$, is reached from save() alone, while the path getter returns path.join(this.server.stacksDir, this.name) and Stack.getStack builds path.join(server.stacksDir, stackName) with no check. The socket handlers in backend/agent-socket-handlers/docker-socket-handler.ts confirm the caller is logged in and that the name is a string, then pass it straight to Stack.getStack, so a name containing traversal sequences resolves outside the managed stacks directory. An authenticated user can therefore read the composeENV and composeYAML values of any directory the server process can reach, which discloses the secrets in that directory's .env or Compose file, and can invoke delete(), which runs docker compose down and then fsAsync.rm on the traversed path with recursive and force set, removing that directory. Disclosure is limited to files named .env or an accepted Compose filename, and deletion requires the target directory to hold a valid Compose file so that docker compose down exits successfully. Dockge commonly runs as root with access to the Docker socket, so the reachable set includes unrelated applications on the host. Instances configured with disableAuth, a supported option that logs the caller in as admin automatically, expose both operations without authentication.
