CVE-2026-107180 için toplanan üretici, dağıtım, yama ve güvenlik kaynağı kayıtlarını karşılaştırıp kanıt bağlantılı bir açıklama hazırlayalım.
On MISP instances configured to require TOTP enrolment (Security.otp_required), the enforcement of the mandatory two-factor authentication setup applied only to standard browser requests. An authenticated user who had not yet enrolled in TOTP could bypass the forced setup by issuing any non-browser request type, including AJAX/XHR calls, REST API requests, .json format URLs, restSearch queries, or automation actions. Because these machine-readable request shapes cannot follow the redirect that the browser path uses to send the user to the TOTP enrolment page, the guard simply skipped the check and the user retained full access to the instance without completing the required second-factor setup. The initial fix (commit 8deb0619e) added a guard specifically for AJAX requests. A follow-up fix (commit 6b527ba6e) broadened the guard to cover every non-browser request shape, while preserving the exemption for identities authenticated via API key (logged_by_authkey flag). Impact: an authenticated user on an otp_required instance can operate with full access indefinitely without enrolling in TOTP, nullifying the instance-level two-factor authentication policy. Affected version: <2.5.48
