Starting in version 4.7.0 and prior to version 4.9.2, when the `verifyMultiProof`, `verifyMultiProofCalldata`, `procesprocessMultiProof`, or `processMultiProofCalldat` functions are in use, it is possible to construct merkle trees that allow forging a valid multiproof for an arbitrary set of leaves.\n\nA contract may be vulnerable if it uses multiproofs for verification and the merkle tree that is processed includes a node with value 0 at depth 1 (just under the root). This could happen inadvertedly for balanced trees with 3 leaves or less, if the leaves are not hashed. This could happen deliberately if a malicious tree builder includes such a node in the tree.\n\nA contract is not vulnerable if it uses single-leaf proving (`verify`, `verifyCalldata`, `processProof`, or `processProofCalldata`), or if it uses multiproofs with a known tree that has hashed leaves. Standard merkle trees produced or validated with the @openzeppelin/merkle-tree library are safe.\n\nThe problem has been patched in version 4.9.2.\n\nSome workarounds are available. For those using multiproofs: When constructing merkle trees hash the leaves and do not insert empty nodes in your trees. Using the @openzeppelin/merkle-tree package eliminates this issue.

This impacts the `Governor` contract in v4.9.0 only, and the `GovernorCompatibilityBravo` contract since v4.3.0. This problem has been patched in 4.9.1 by introducing opt-in frontrunning protection. Users are advised to upgrade. Users unable to upgrade may submit the proposal creation transaction to an endpoint with frontrunning protection as a workaround.","references":[{"reference_url":"https://api.first.org/data/v1/epss?cve=CVE-2023-34234","reference_id":"","reference_type":"","scores":[{"value":"0.00108","scoring_system":"epss","scoring_elements":"0.28689","published_at":"2026-06-05T12:55:00Z"},{"value":"0.00108","scoring_system":"epss","scoring_elements":"0.28648","published_at":"2026-06-06T12:55:00Z"}],"url":"https://api.first.org/data/v1/epss?cve=CVE-2023-34234"},{"reference_url":"https://github.com/OpenZeppelin/openzeppelin-contracts","reference_id":"","reference_type":"","scores":[{"value":"5.3","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L"},{"value":"MODERATE","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://github.com/OpenZeppelin/openzeppelin-contracts"},{"reference_url":"https://github.com/OpenZeppelin/openzeppelin-contracts/commit/d9474327a492f9f310f31bc53f38dbea56ed9a57","reference_id":"","reference_type":"","scores":[{"value":"5.3","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L"},{"value":"MODERATE","scoring_system":"generic_textual","scoring_elements":""},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:Y/T:P/P:M/B:A/M:M/D:T/2025-01-06T20:13:05Z/"}],"url":"https://github.com/OpenZeppelin/openzeppelin-contracts/commit/d9474327a492f9f310f31bc53f38dbea56ed9a57"},{"reference_url":"https://github.com/OpenZeppelin/openzeppelin-contracts/releases/tag/v4.9.1","reference_id":"","reference_type":"","scores":[{"value":"5.3","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L"},{"value":"MODERATE","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://github.com/OpenZeppelin/openzeppelin-contracts/releases/tag/v4.9.1"},{"reference_url":"https://github.com/OpenZeppelin/openzeppelin-contracts-upgradeable/commit/66f390fa516b550838e2c2f65132b5bc2afe1ced","reference_id":"","reference_type":"","scores":[{"value":"5.3","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L"},{"value":"MODERATE","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://github.com/OpenZeppelin/openzeppelin-contracts-upgradeable/commit/66f390fa516b550838e2c2f65132b5bc2afe1ced"},{"reference_url":"https://nvd.nist.gov/vuln/detail/CVE-2023-34234","reference_id":"CVE-2023-34234","reference_type":"","scores":[{"value":"5.3","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L"},{"value":"MODERATE","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://nvd.nist.gov/vuln/detail/CVE-2023-34234"},{"reference_url":"https://github.com/advisories/GHSA-5h3x-9wvq-w4m2","reference_id":"GHSA-5h3x-9wvq-w4m2","reference_type":"","scores":[],"url":"https://github.com/advisories/GHSA-5h3x-9wvq-w4m2"},{"reference_url":"https://github.com/OpenZeppelin/openzeppelin-contracts/security/advisories/GHSA-5h3x-9wvq-w4m2","reference_id":"GHSA-5h3x-9wvq-w4m2","reference_type":"","scores":[{"value":"5.3","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L"},{"value":"MODERATE","scoring_system":"generic_textual","scoring_elements":""},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:Y/T:P/P:M/B:A/M:M/D:T/2025-01-06T20:13:05Z/"}],"url":"https://github.com/OpenZeppelin/openzeppelin-contracts/security/advisories/GHSA-5h3x-9wvq-w4m2"}],"fixed_packages":[{"url":"http://public2.vulnerablecode.io/api/packages/65334?format=json","purl":"pkg:npm/%40openzeppelin/contracts-upgradeable@4.9.1","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-n62w-34wv-rbdn"},{"vulnerability":"VCID-rgdr-jxdc-hucn"},{"vulnerability":"VCID-wvaj-hpg7-jbag"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:npm/%2540openzeppelin/contracts-upgradeable@4.9.1"}],"aliases":["CVE-2023-34234","GHSA-5h3x-9wvq-w4m2"],"risk_score":3.1,"exploitability":"0.5","weighted_severity":"6.2","resource_url":"http://public2.vulnerablecode.io/vulnerabilities/VCID-mshr-yc9h-jufk"}],"risk_score":"3.1","resource_url":"http://public2.vulnerablecode.io/packages/pkg:npm/%2540openzeppelin/contracts-upgradeable@4.9.1"}
