{"id":"CVE-2021-25835","details":"Cosmos Network Ethermint \u003c= v0.4.0 is affected by a cross-chain transaction replay vulnerability in the EVM module. Since ethermint uses the same chainIDEpoch and signature schemes with ethereum for compatibility, a verified signature in ethereum is still valid in ethermint with the same msg content and chainIDEpoch, which enables \"cross-chain transaction replay\" attack.","aliases":["GHSA-x5f3-qmwj-4f84","GO-2022-0889"],"modified":"2026-07-09T01:06:27.234802Z","published":"2021-02-08T18:15:13.803Z","references":[{"type":"ADVISORY","url":"https://github.com/cosmos/ethermint/issues/687"},{"type":"FIX","url":"https://github.com/cosmos/ethermint/pull/692"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/cosmos/ethermint","events":[{"introduced":"0"},{"last_affected":"11e2f636787f453dac645b53e6b930d42bbb8711"}],"database_specific":{"cpe":"cpe:2.3:a:chainsafe:ethermint:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"last_affected":"0.4.0"}],"source":"CPE_RANGE"}}],"versions":["v0.4.0","v0.3.0","v0.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2021-25835.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N"}]}
