{"id":"CVE-2023-34458","aliases":["GHSA-j494-7x2v-vvvp","GO-2023-1912"],"url":"https://o3.security/vulnerability/CVE-2023-34458","summary":"mx-chain-go's relayed transactions always increment nonce","details":"mx-chain-go is the official implementation of the MultiversX blockchain protocol, written in golang. When executing a relayed transaction, if the inner transaction failed, it would have increased the inner transaction's sender account nonce. This could have contributed to a limited DoS attack on a targeted account. The fix is a breaking change so a new flag `RelayedNonceFixEnableEpoch` was needed. This was a strict processing issue while validating blocks on a chain. This vulnerability has been patched in version 1.4.17.","published":"2023-07-13T18:45:03.499Z","modified":"2026-08-12T03:51:41.158317119Z","cvss":{"score":7.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:L/A:H"},"epss":{"score":0.0132,"percentile":0.68651,"asOf":"2026-08-21"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/multiversx/mx-chain-go","fixedVersion":"1.4.17"}],"fix":{"url":"https://github.com/multiversx/mx-chain-go/commit/babdb144f1316ab6176bf3dbd7d4621120414d43","label":"multiversx/mx-chain-go@babdb14"},"references":[{"type":"WEB","url":"https://github.com/multiversx/mx-chain-go/blob/babdb144f1316ab6176bf3dbd7d4621120414d43/integrationTests/vm/txsFee/relayedMoveBalance_test.go#LL165C14-L165C14"},{"type":"WEB","url":"https://github.com/multiversx/mx-chain-go/releases/tag/v1.4.17"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/34xxx/CVE-2023-34458.json"},{"type":"ADVISORY","url":"https://github.com/multiversx/mx-chain-go/security/advisories/GHSA-j494-7x2v-vvvp"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-34458"},{"type":"FIX","url":"https://github.com/multiversx/mx-chain-go/commit/babdb144f1316ab6176bf3dbd7d4621120414d43"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:41.158317119Z"}}
