    frost-core: refresh shares with smaller min_signers will reduce security of group

    CVE-2025-58359 · GHSA-wgq8-vr6r-mqxm

    Affected
    • crates.io frost-core >= 2.0.0, < 2.2.0

    2.2.0· Vendor fix available
    Issue
    Impact It was not clear that it is not possible to change minsigners (i.e. the threshold) with the refresh share functionality (frostcore::keys::refresh module). Using a smaller value would not decrease the threshold, and attempts to sign using a smaller threshold would fail. Additionally, after refreshing the shares with a smaller threshold, it would still be possible to sign with the original threshold; however, this could cause a security loss to the participant's shares. We have not determined the exact security implications of doing so and judged simpler to just validate minsigners. If for some reason you have done a refresh share procedure with a smaller minsigners we strongly recommend migrating to a new key. Patches Updating to 2.2.0 will ensure that the minsigners parameter will be validated. However it won't restore the security of groups refreshed with a smaller minsigners parameters. Workarounds You don't need to update if you don't use the refresh share functionality, or…

    Recommended action: Upgrade to 2.2.0 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
