CVE-2026-86840
UnknownSummary
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.
Risk Assessment
The risk includes manipulation of commission settlements, which may lead to financial losses for the protocol and unfair enrichment of the attacker at the expense of other participants.
Recommendation
It is recommended to immediately upgrade Bifrost to a version containing a fix and to implement proper authorization controls in the `vtoken-minting` and `slpx` pallets.
Other vulnerabilities in Bifrost
See all- CVE-2026-86242High
Bifrost HTTP transport before 2.0.0 accepts an enabled custom plugin whose path is an HTTP URL through unauthenticated POST /api/plugins when management authentication is disabled. The shared-object loader treats an http-prefixed path as a download URL, writes the body to a temporary .so, and passes it to plugin.Open. On dynamically linked builds this is unauthenticated remote code execution; on the static Docker image it is only SSRF.
- CVE-2026-55245High
Bifrost before version 1.5.17 incorrectly classifies addresses from CGNAT, 6to4, NAT64, and fec0::/10 ranges as public. An attacker controlling a multimodal request URL can make the gateway fetch internal services, including cloud instance metadata.
