# Patch Next advisory brief: CVE-2022-35915

Advisory: OpenZeppelin Contracts ERC165Checker unbounded gas consumption
IDs: CVE-2022-35915, GHSA-7grf-83vw-6f5x
Record: https://patchnext.com/advisories/cve-2022-35915 (revision 2, source checked 26 Oct 2026, 12:22 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 5.3)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Partial vendor fix; fixed versions by package: @openzeppelin/contracts 4.7.2; @openzeppelin/contracts-upgradeable 4.7.2. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm @openzeppelin/contracts: affected >= 2.0.0, < 4.7.2; fixed in 4.7.2
- npm @openzeppelin/contracts-upgradeable: affected >= 3.2.0, < 4.7.2; fixed in 4.7.2
- npm openzeppelin-solidity: affected >= 2.0.0, <= 4.6.0
- npm openzeppelin-eth: affected >= 2.0.0, <= 2.2.0

## Suggested inspection (read-only)
- `npm ls @openzeppelin/contracts --all`: lists every installed copy and version, including transitive ones. Run in the project root after `npm ci`.
- `npm ls @openzeppelin/contracts-upgradeable --all`: lists every installed copy and version, including transitive ones. Run in the project root after `npm ci`.
- `npm ls openzeppelin-solidity --all`: lists every installed copy and version, including transitive ones. Run in the project root after `npm ci`.
- `npm ls openzeppelin-eth --all`: lists every installed copy and version, including transitive ones. Run in the project root after `npm ci`.

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on @openzeppelin/contracts, @openzeppelin/contracts-upgradeable, openzeppelin-solidity, openzeppelin-eth.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
