EUVD Vulnerability Catalog
EUVD-2026-78333
Severity: MEDIUM
Base Score: 5.3
CVSS Version: 4.0
Vulnerability Description
Affected versions of MISP incorrectly filter dashboard templates that are restricted to a specific permission flag.
DashboardsController::listTemplates() allowed a template when either:
- its restrict_to_permission_flag matched one of the current user’s permission flags, or
- restrict_to_permission_flag equaled integer 0
However, restrict_to_permission_flag is a varchar. MySQL therefore performed numeric coercion when comparing the column against integer 0. Strings such as perm_site_admin convert numerically to zero, making expressions such as perm_site_admin = 0 evaluate true and causing the “unrestricted” branch to match permission-restricted templates as well.
Version affected: ≤2.5.45
