This could enable them to modify site configurations, install malicious plugins, steal sensitive data, or even completely compromise the server.

The primary mitigation for CVE-2026-23800 is to immediately upgrade Modular DS to version 2.6.0 or later. If upgrading is not immediately feasible due to compatibility issues or breaking changes, consider implementing stricter access controls and limiting user privileges. While a direct workaround is unavailable, reviewing and restricting user permissions can reduce the potential impact. After upgrading, confirm the fix by attempting to execute commands with a low-privilege user and verifying that privilege escalation is prevented.
