In versions 2.0.0 through 2.1.0, refresh shares with smaller min_signers will reduce security of group. The inability to change min_signers (i.e. the threshold) with the refresh share functionality (frost_core::keys::refresh module) was not made clear to users. 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, potentially causing a security loss to the participant&#8217;s shares. This issue is fixed in version 2.2.0.<br \/>\n<br \/>\n<strong>Severity:<\/strong> 6.0 | MEDIUM<br \/>\n<br \/>\nVisit the link for more details, such as CVSS details, affected products, timeline, and more&#8230;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>CVE ID : CVE-2025-58359 Published : Sept. 5, 2025, 12:15 a.m. | 58\u00a0minutes ago Description : ZF FROST is a Rust implementation of FROST (Flexible Round-Optimised Schnorr Threshold signatures).
