CVE-2026-54362 Details
Description
An incorrect visibility condition in the MISP event template builder allowed authenticated non-site-admin users to view galaxies that should not have been visible to their organisation. The custom access-control condition intended to restrict galaxies to those owned by the user’s organisation or distributed beyond it used a PHP comparison expression instead of a query condition. As a result, enabled galaxies, including organisation-only custom galaxies belonging to other organisations, could be exposed in the template builder galaxy list. This could disclose metadata about private galaxy definitions to unauthorised users.
A vulnerability in the MISP event template builder allowed authenticated non-site-admin users to access galaxies that should have been restricted to their organization. The issue arose from a flawed visibility condition that used a PHP comparison instead of a proper query condition, inadvertently exposing galaxies, including private ones from other organizations, in the template builder. This misconfiguration could lead to unauthorized disclosure of metadata related to private galaxy definitions.
Users can update to MISP version 2.5.40, where this vulnerability has been addressed.
