Contract-state modification via persistent read-only writes
Published Sep 6, 2022 · Updated Apr 22, 2025
Improper VM state isolation in MultiversX mx-chain-go before 1.3.35 allows remote attackers to alter contract state through read-only calls. The VM permits a contract invoked in read-only mode to emit smart-contract results and persist changes to the callee instead of discarding those writes. An attacker must submit an interaction that reaches a state-changing callee through a read-only cross-contract call, enabling unintended ledger-state modification without reported service interruption.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
