CVE-2026-82804 · Severity: info · Published 2026-09-29

Apache DolphinScheduler, a workflow scheduling and management platform, contains a shell injection vulnerability in its Alert Script plugin. An authenticated user can create resources with specially crafted filenames containing shell commands, which are then executed with the privileges of the DolphinScheduler service when the alert script runs. This allows an attacker to execute arbitrary commands on the server hosting the service.

Technologies: [Apache DolphinScheduler](https://junglewise.ai/threats/technologies/apache-dolphinscheduler-1). Vendors: [Apache](https://junglewise.ai/threats/vendors/apache).

**How is CVE-2026-82804 attacked?** It is attacked over the network, in a hosted service.

**Am I affected by CVE-2026-82804?** Check whether you run Apache DolphinScheduler at an affected version. Junglewise does that check for you around the clock: connect your code, cloud and domains, and it matches new vulnerabilities like this one against what you actually run and tells you when one reaches you.

## Technical details

The scriptPath parameter in the Alert Script plugin's /test-send endpoint is passed unsanitized into a /bin/sh -c command, allowing shell metacharacter injection (e.g., $(...) for command substitution). An authenticated attacker can exploit this by creating a resource with a filename containing shell command syntax; when the alert script executes, the injected commands run with DolphinScheduler service privileges. The vulnerability requires authentication and a fix is available in version 3.4.3.
