CVE-2026-86840

The vtoken-minting and slpx pallets in Bifrost contain an improper authorization vulnerability in channel commission attribution. A signed account can supply an arbitrary registered channel id when minting tokens without verifying that the caller is authorized to mint on behalf of that channel. This allows an attacker to inflate a channel's recorded mint volume and cause protocol commission payments to be disproportionately distributed to that channel during commission settlement.
