What is CVE-2026-54362?
CVE-2026-54362 is a medium-severity missing authorization vulnerability in misp, published on 12 Jun 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official 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.
