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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","score":5.3},"cwes":["CWE-400"],"references":["https://github.com/multiversx/mx-chain-go/blob/babdb144f1316ab6176bf3dbd7d4621120414d43/integrationTests/vm/txsFee/relayedMoveBalance_test.go#LL165C14-L165C14","https://github.com/multiversx/mx-chain-go/commit/babdb144f1316ab6176bf3dbd7d4621120414d43","https://github.com/multiversx/mx-chain-go/releases/tag/v1.4.17","https://github.com/multiversx/mx-chain-go/security/advisories/GHSA-j494-7x2v-vvvp","https://github.com/multiversx/mx-chain-go/blob/babdb144f1316ab6176bf3dbd7d4621120414d43/integrationTests/vm/txsFee/relayedMoveBalance_test.go#LL165C14-L165C14"],"products":["multiversx:mx-chain-go"],"source":"nvd","synced_at":"2026-10-19T21:38:35.729974749+00:00"},"epss":{"cve":"CVE-2023-34458","score":0.0132,"percentile":0.70859,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-j494-7x2v-vvvp","url":"https://osv.dev/vulnerability/GHSA-j494-7x2v-vvvp","summary":"mx-chain-go's relayed transactions always increment nonce","modified":"2024-08-20T20:58:44.223725Z","packages":[{"ecosystem":"Go","name":"github.com/multiversx/mx-chain-go","purl":"pkg:golang/github.com/multiversx/mx-chain-go","ranges":["<1.4.17"],"fixed":["1.4.17"]}]},{"id":"GO-2023-1912","url":"https://osv.dev/vulnerability/GO-2023-1912","summary":"mx-chain-go's relayed transactions always increment nonce in github.com/multiversx/mx-chain-go","modified":"2026-03-03T04:54:00.141543Z","packages":[{"ecosystem":"Go","name":"github.com/multiversx/mx-chain-go","purl":"pkg:golang/github.com/multiversx/mx-chain-go","ranges":["<1.4.17"],"fixed":["1.4.17"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
