Since the vulnerability is conditional on ADMIN_PASSWORD being set, administrators should verify the configuration and restrict network access to the MISP Modules website. Monitor vendor advisories for official fixes or updates.
Description
CVE-2026-127016 is a critical missing authorization vulnerability in the MISP Modules website component. Specifically, the external tools management endpoints (add, delete, change status, and change configuration) do not enforce administrator authentication when ADMIN_PASSWORD is set, allowing unauthenticated attackers with network access to manipulate external tools arbitrarily. This includes adding new tools, deleting existing ones, toggling their active status, and modifying configurations such as API keys and ingestion URLs. The vulnerability affects the external_tools Flask blueprint within the MISP Modules website application. Installations without an admin password are not vulnerable as open management access is by design.
