This could cause issues when WAL entries are being read during consensus as an arbitrary etcd consensus participant could go down from a runtime panic when reading the entry.","published":"2020-08-05T20:15:14.553Z","modified":"2026-07-08T06:27:12.729166492Z","cvss":{"score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"},"epss":{"score":0.01256,"percentile":0.66764,"asOf":"2026-08-23"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"go.etcd.io/etcd/v3","fixedVersion":"3.3.23"},{"ecosystem":"Go","name":"go.etcd.io/etcd/v3","fixedVersion":"3.4.10"}],"fix":null,"references":[{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/L6B6R43Y7M3DCHWK3L3UVGE2K6WWECMP/"},{"type":"ADVISORY","url":"https://github.com/etcd-io/etcd/security/advisories/GHSA-m332-53r6-2w93"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-08T06:27:12.729166492Z"}}
