Description · from the CVE record

Elrond go is the go implementation for the Elrond Network protocol. In versions prior to 1.3.35, read only calls between contracts can generate smart contracts results. For example, if contract A calls in read only mode contract B and the called function will make changes upon the contract's B state, the state will be altered for contract B as if the call was not made in the read-only mode. This can lead to some effects not designed by the original smart contracts programmers. This issue was patched in version 1.3.35. There are no known workarounds.
