Prior to 0.3.1, the ERC7984 contract tracked confidential total supply with an euint64 value, and an overflowing internal _mint operation could fail silently. The wrap and onTransferReceived functions in contracts/token/ERC7984/extensions/ERC7984ERC20Wrapper.sol did not handle that failure, so a user could transfer the underlying token without receiving the corresponding confidential wrapped token. With the default rate(), the wrapper fills after approximately 18.4 trillion tokens, and subsequent wrapping requests can cause loss of funds. This issue is fixed in version 0.3.1.","state":0,"publishedAt":"2026-08-13T18:18:20.277+00:00","modifiedAt":"2026-10-24T15:10:00.19+00:00","affected":[],"metrics":[{"system":"CVSS 4.0 · security-advisories@github.com · Secondary","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","score":6.6,"severity":"MEDIUM"}],"references":["https://github.com/OpenZeppelin/openzeppelin-confidential-contracts/commit/c620d4386021dde63ae3ea1507dee8543791134a","https://github.com/OpenZeppelin/openzeppelin-confidential-contracts/pull/271","https://github.com/OpenZeppelin/openzeppelin-confidential-contracts/releases/tag/v0.3.1","https://github.com/OpenZeppelin/openzeppelin-confidential-contracts/security/advisories/GHSA-hqf9-8xv5-x8xw"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-73645","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-190"],"productCriteria":[],"sourceDates":{"published":"2026-08-13T18:18:20.277","lastModified":"2026-10-24T15:10:00.190"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
