CVE-2026-82804: CWE-78 Improper neutralization of special elements used in an OS command ('OS command injection') in Apache Software Foundation Apache DolphinScheduler
CVE-2026-82804 is an OS command injection vulnerability in Apache DolphinScheduler before version 3.4.3. The flaw arises because the scriptPath parameter is used in a shell command without proper neutralization of special shell characters, allowing an authenticated user to execute arbitrary commands. Exploitation involves creating a resource with a filename containing shell command substitution syntax and triggering the Alert Script plugin's /test-send endpoint. The vulnerability is fixed in version 3.4.3.
AI Analysis
Technical Summary
Apache DolphinScheduler versions prior to 3.4.3 contain an OS command injection vulnerability (CWE-78) due to insufficient sanitization of the scriptPath parameter in shell commands. An authenticated attacker can craft a filename with shell metacharacters (e.g., $(...)) that, when passed to the Alert Script plugin's /test-send endpoint, results in arbitrary command execution with the DolphinScheduler service's privileges. This allows execution of commands on the underlying operating system, posing a significant security risk. The issue is resolved in version 3.4.3.
Potential Impact
Successful exploitation allows an authenticated user to execute arbitrary OS commands with the privileges of the DolphinScheduler service process. This can lead to unauthorized system access, data compromise, or further system manipulation depending on the service's privileges.
Mitigation Recommendations
Users should upgrade Apache DolphinScheduler to version 3.4.3 or later, which contains the official fix for this vulnerability. No other mitigations are indicated by the vendor advisory.
