Description
CVE-2026-82804 is a high-severity OS command injection vulnerability in Apache DolphinScheduler before version 3.4.3. It arises from insufficient neutralization of shell metacharacters in the scriptPath parameter used in a shell command. An authenticated user can exploit this by crafting a resource filename with shell command substitution syntax, leading to arbitrary command execution with DolphinScheduler service privileges. The issue is fixed in version 3.4.3.
