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.","published":"2026-09-08T16:18:37.597","modified":"2026-09-10T19:17:36.980","cvss":{"score":9.1,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://docs.bifrost.io/faq/what-are-vtokens"},{"type":"WEB","url":"https://gist.github.com/prasanna8585/ffd112b1a125ca4c5533fdce45ef57c1"},{"type":"WEB","url":"https://gist.github.com/prasanna8585/ffd112b1a125ca4c5533fdce45ef57c1"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-09-10T19:17:36.980"}}
