# Patch Next advisory brief: CVE-2022-0609

Advisory: Use after free in Animation
IDs: CVE-2022-0609, GHSA-vv6j-ww6x-54gx
Record: https://patchnext.com/advisories/cve-2022-0609 (revision 1, source checked 26 Oct 2026, 16:59 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.8)
Exploitation: confirmed: listed in the CISA Known Exploited Vulnerabilities catalog.
Vendor response: Vendor fix available; fixed versions by package: cefsharp.wpf.hwndhost 98.1.210; cefsharp.common.netcore 98.1.210; cefsharp.common 98.1.210; cefsharp.wpf.netcore 98.1.210; cefsharp.wpf 98.1.210; cefsharp.winforms.netcore 98.1.210; cefsharp.offscreen 98.1.210; cefsharp.winforms 98.1.210; cefsharp.offscreen.netcore 98.1.210. A vendor fix does not mean a deployment is fixed.

## Affected components
- NuGet cefsharp.wpf.hwndhost: affected <= 98.1.190; fixed in 98.1.210
- NuGet cefsharp.common.netcore: affected <= 98.1.190; fixed in 98.1.210
- NuGet cefsharp.common: affected <= 98.1.190; fixed in 98.1.210
- NuGet cefsharp.wpf.netcore: affected <= 98.1.190; fixed in 98.1.210
- NuGet cefsharp.wpf: affected <= 98.1.190; fixed in 98.1.210
- NuGet cefsharp.winforms.netcore: affected <= 98.1.190; fixed in 98.1.210
- NuGet cefsharp.offscreen: affected <= 98.1.190; fixed in 98.1.210
- NuGet cefsharp.winforms: affected <= 98.1.190; fixed in 98.1.210
- NuGet cefsharp.offscreen.netcore: affected <= 98.1.190; fixed in 98.1.210

## Suggested inspection (read-only)
- NuGet cefsharp.wpf.hwndhost: check the installed version with your package manager.
- NuGet cefsharp.common.netcore: check the installed version with your package manager.
- NuGet cefsharp.common: check the installed version with your package manager.
- NuGet cefsharp.wpf.netcore: check the installed version with your package manager.
- NuGet cefsharp.wpf: check the installed version with your package manager.
- NuGet cefsharp.winforms.netcore: check the installed version with your package manager.
- NuGet cefsharp.offscreen: check the installed version with your package manager.
- NuGet cefsharp.winforms: check the installed version with your package manager.
- NuGet cefsharp.offscreen.netcore: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on cefsharp.wpf.hwndhost, cefsharp.common.netcore, cefsharp.common, cefsharp.wpf.netcore, cefsharp.wpf, cefsharp.winforms.netcore, cefsharp.offscreen, cefsharp.winforms, cefsharp.offscreen.netcore.
- 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?
- Mark the work resolved only after the fixed version is verified in production.
