CVE-2026-127016 in misp-modules
LogPulse has a published detection rule for this CVE: it raises a notable when someone tries to exploit it.
What the vulnerability is
The MISP Modules website component exposes external tool management endpoints (add, delete, change status, and change configuration) that did not enforce the optional administrator authentication policy. When ADMIN_PASSWORD was configured in the application environment, the module configuration endpoints correctly required an authenticated administrator session, but the external tools management handlers processed requests from anonymous users without any authorization check. An unauthenticated attacker with network access to the website could add arbitrary external tools, delete existing tools, toggle their active status, and modify their configurations including API keys and ingestion URLs. This inconsistency allowed bypass of the intended access control for the external tools management functionality. The vulnerability is conditional on ADMIN_PASSWORD being set; installations without an admin password intentionally permit open management access by design. The affected component is the external_tools Flask blueprint within the MISP Modules website application.
