Detailsinfo

A vulnerability was found in OpenZeppelin Contracts up to 4.8.3 and classified as problematic. Affected by this issue is some unknown processing of the component Proposal Creation Entrypoint. The manipulation with an unknown input leads to a input validation vulnerability. Using CWE to declare the problem leads to CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. Impacted is confidentiality, integrity, and availability. CVE summarizes:

OpenZeppelin Contracts is a library for secure smart contract development. The proposal creation entrypoint (`propose`) in `GovernorCompatibilityBravo` allows the creation of proposals with a `signatures` array shorter than the `calldatas` array. This causes the additional elements of the latter to be ignored, and if the proposal succeeds the corresponding actions would eventually execute without any calldata. The `ProposalCreated` event correctly represents what will eventually execute, but the proposal parameters as queried through `getActions` appear to respect the original intended calldata. This issue has been patched in 4.8.3. As a workaround, ensure that all proposals that pass through governance have equal length `signatures` and `calldatas` parameters.

The weakness was presented 04/16/2023 as GHSA-93hq-5wgc-jc82. The advisory is shared for download at github.com. This vulnerability is handled as CVE-2023-30542 since 04/12/2023. Successful exploitation requires user interaction by the victim. There are neither technical details nor an exploit publicly available.

Upgrading to version 4.8.3 eliminates this vulnerability. The upgrade is hosted for download at github.com.
