As a result, any contract using `is_valid_eth_signature` from the account library (such as the `EthAccount` preset) is vulnerable to a malicious sequencer. Specifically, the malicious sequencer would be able to bypass signature validation to impersonate an instance of these accounts. The issue has been patched in 0.6.1."}]}, "problemtype": {"problemtype_data": [{"description": [{"lang": "en", "value": "CWE-347"}]}]}, "data_version": "4.0", "CVE_data_meta": {"ID": "CVE-2023-23940", "ASSIGNER": "security-advisories@github.com"}}, "impact": {"baseMetricV3": {"cvssV3": {"scope": "UNCHANGED", "version": "3.1", "baseScore": 5.3, "attackVector": "NETWORK", "baseSeverity": "MEDIUM", "vectorString": "CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N", "integrityImpact": "NONE", "userInteraction": "NONE", "attackComplexity": "HIGH", "availabilityImpact": "NONE", "privilegesRequired": "LOW", "confidentialityImpact": "HIGH"}, "impactScore": 3.6, "exploitabilityScore": 1.6}}, "publishedDate": "2023-02-03T20:15Z", "configurations": {"nodes": [{"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:a:openzeppelin:contracts:*:*:*:*:*:cairo:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "0.6.1", "versionStartIncluding": "0.2.0"}]}], "CVE_data_version": "4.0"}, "lastModifiedDate": "2023-02-13T15:11Z"}
