The current sources do not mark it as known exploited. The current feed maps MISP/MISP (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
A CVSS score is not reported in the current record. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

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
