CVE-2026-73162

cti-transmute CSRF Allows Unauthorized Follow and Notification State Changes

Published Aug 11, 2026 CVSS 4.0 · 5.3 Medium EPSS < 1% KEV · Not listed
Description
Affected versions of MISP cti-transmute expose several state-changing account operations as GET requests:



*
/account/follow


*
/account/delete_notification


*
/account/mark_notification_read


*
/account/mark_all_read





These endpoints require authentication, but before the fix they could be invoked with simple GET requests. That makes them susceptible to cross-site request forgery because a third-party site can induce the victim’s browser to send authenticated GET requests automatically.


The patch converts the actions to POST or DELETE and updates the frontend to include an X-CSRFToken header, providing explicit CSRF protection for those state-changing operations.
