  "title": "Improper authorization in Mailu account management",
  "summary": "Mailu deployments built before the corrective commit are affected by an authorization flaw in account-management actions. A domain manager may be able to assume a more privileged account by resetting its credentials or obtaining its tokens; this requires an existing domain-manager account and a higher-privileged target account.",
  "mitigation": "Update Mailu to a current master build that includes commit 8577c929b4ade04d3cd4210cf036601abd793556. Until updated, restrict domain-manager access and review privileged-account credentials and active tokens.",
