Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2023-30542 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- @openzeppelin/contracts (npm): affected from 4.3.0; fixed in 4.8.3\n- @openzeppelin/contracts (npm): affected from 4.3.0; fixed in 4.8.3\n- @openzeppelin/contracts-upgradeable (npm): affected from 4.3.0; fixed in 4.8.3\n- @openzeppelin/contracts-upgradeable (npm): affected from 4.3.0; fixed in 4.8.3\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2023-30542/ (Markdown: https://insights.sbomify.com/CVE-2023-30542/index.md)","id":"CVE-2023-30542","markdown":"https://insights.sbomify.com/CVE-2023-30542/index.md","name":"CVE-2023-30542","record":{"aliases":["GHSA-93hq-5wgc-jc82"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Smart contract library","requires_auth":"low_privilege","summary":"Attackers can create governance proposals with mismatched array lengths, causing actions to execute without intended calldata, potentially altering contract state unexpectedly.","user_interaction":"required","vuln_class":"business_logic"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"contracts","vendor":"openzeppelin"},{"product":"contracts_upgradeable","vendor":"openzeppelin"}],"cvss":{"score":6.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:L/I:H/A:L","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"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.","ecosystems":["npm"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"GovernorCompatibilityBravo may trim proposal calldata","id":"CVE-2023-30542","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"business_logic","year":"2023"},"n_packages":4,"n_references":2,"next":{"headline":"`chainId` may be outdated if user changes chains as part of connection in @web3-react","id":"CVE-2023-30543"},"packages":[{"ecosystem":"npm","fixed":["4.8.3"],"introduced":["4.3.0"],"last_affected":[],"package":"@openzeppelin/contracts","purl":null,"source":"GHSA-93hq-5wgc-jc82"},{"ecosystem":"npm","fixed":["4.8.3"],"introduced":["4.3.0"],"last_affected":[],"package":"@openzeppelin/contracts","purl":"pkg:npm/%40openzeppelin/contracts","source":"GHSA-93hq-5wgc-jc82"},{"ecosystem":"npm","fixed":["4.8.3"],"introduced":["4.3.0"],"last_affected":[],"package":"@openzeppelin/contracts-upgradeable","purl":null,"source":"GHSA-93hq-5wgc-jc82"},{"ecosystem":"npm","fixed":["4.8.3"],"introduced":["4.3.0"],"last_affected":[],"package":"@openzeppelin/contracts-upgradeable","purl":"pkg:npm/%40openzeppelin/contracts-upgradeable","source":"GHSA-93hq-5wgc-jc82"}],"prev":{"headline":"TransparentUpgradeableProxy clashing selector calls may not be delegated in @openzeppelin/contracts","id":"CVE-2023-30541"},"products":["openzeppelin-contracts"],"published":"2023-04-16","related":[{"cvss_score":10,"headline":"TimelockController vulnerability in OpenZeppelin Contracts","id":"CVE-2021-39167","kev_date_added":null,"published":"2021-08-26"},{"cvss_score":10,"headline":"TimelockController vulnerability in OpenZeppelin Contracts","id":"CVE-2021-39168","kev_date_added":null,"published":"2021-08-26"},{"cvss_score":9.8,"headline":"UUPSUpgradeable vulnerability in OpenZeppelin Contracts","id":"CVE-2021-41264","kev_date_added":null,"published":"2021-11-12"},{"cvss_score":7.9,"headline":"ECDSA signature malleability in OpenZeppelin Contracts","id":"CVE-2022-35961","kev_date_added":null,"published":"2022-08-14"},{"cvss_score":7.5,"headline":"GovernorVotesQuorumFraction updates to quorum may affect past defeated proposals in @openzeppelin/contracts","id":"CVE-2022-31198","kev_date_added":null,"published":"2022-08-01"},{"cvss_score":7.5,"headline":"OpenZeppelin Contracts's ERC165Checker may revert instead of returning false","id":"CVE-2022-31170","kev_date_added":null,"published":"2022-07-21"},{"cvss_score":7.5,"headline":"OpenZeppelin Contracts's SignatureChecker may revert on invalid EIP-1271 signers","id":"CVE-2022-31172","kev_date_added":null,"published":"2022-07-21"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-02-06","vendors":["OpenZeppelin"]},"summary":"Attackers can create governance proposals with mismatched array lengths, causing actions to execute without intended calldata, potentially altering contract state unexpectedly.","url":"https://insights.sbomify.com/CVE-2023-30542/"}
