This requires the user to set any environment variable in a different thread than the affected functions. The affected functions are time::UtcOffset::local_offset_at, time::UtcOffset::try_local_offset_at, time::UtcOffset::current_local_offset, time::UtcOffset::try_current_local_offset, time::OffsetDateTime::now_local and time::OffsetDateTime::try_now_local. Non-Unix targets are unaffected. This includes Windows and wasm. The issue was introduced in version 0.2.7 and fixed in version 0.2.23.","published":"2020-11-24T22:15:11.657Z","modified":"2026-07-09T00:06:53.986708Z","cvss":{"score":5.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"crates.io","name":"time","fixedVersion":"0.2.23"},{"ecosystem":"crates.io","name":"time","fixedVersion":"0.2.23"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://crates.io/crates/time/0.2.23"},{"type":"REPORT","url":"https://github.com/time-rs/time/issues/293"},{"type":"FIX","url":"https://github.com/time-rs/time/security/advisories/GHSA-wcg3-cvx6-7396"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-09T00:06:53.986708Z"}}
