CVE-2026-82804

Unknown

Last modified

CVE-2026-82804 is a vulnerability of currently unknown severity. The scriptPath parameter is incorporated into a /bin/sh -c command without sufficient neutralization of shell metacharacters, allowing shell command substitution and execution. An authenticated user can exploit this behavior by creating a resource whose filename contains shell command substitution syntax, such as $(...), and subsequently supplying the resulting path to the Alert Script plugin's /test-send endpoint. When the alert script is executed, the shell interprets the injected command, resulting in arbitrary command execution with the privileges of the DolphinScheduler service process. This issue affects Apache DolphinScheduler: before 3.4.3. Users are recommended to upgrade to version 3.4.3, which fixes the issue..
