Stale copy of the public suffix list

GHSA-w4x6-hh3x-wjrx

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (gsemac.net 0.38.2), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

Source description

As published by the source; long descriptions are shortened.

We have identified that this project contains an out-of-date version of the Public Suffix List (https://publicsuffix.org/). We are carrying out research to identify the potential impacts of using old versions of the Public Suffix List, and we intend to publish our results in academic conferences and journals. Our results will become publicly available after 21 days; this provides time to update your project with an up-to-date version of the Public Suffix List. GitHub repository: gsemac/Gsemac.Common Public Suffix List path: src/Gsemac.Net/Resources/publicsuffixlist.dat The Public Suffix List is regularly updated (generally a few times per week), and to ensure that the correct privacy boundaries are maintained between websites, applications that use it should routinely fetch an updated copy. If new suffixes are added to the list, and an old list is then used, privacy boundaries will not be constructed correctly, allowing for data (e.g., cookies) to be set incorrectly, potentially…

# Patch Next advisory brief: GHSA-w4x6-hh3x-wjrx

Advisory: Stale copy of the public suffix list
IDs: GHSA-w4x6-hh3x-wjrx
Record: https://patchnext.com/advisories/ghsa-w4x6-hh3x-wjrx (revision 1, source checked 26 Oct 2026, 17:00 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Unrated
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: gsemac.net 0.38.2. A vendor fix does not mean a deployment is fixed.

## Affected components
- NuGet gsemac.net: affected < 0.38.2; fixed in 0.38.2

## Suggested inspection (read-only)
- NuGet gsemac.net: 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 gsemac.net.
- 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.

## Sources
- Verified: https://github.com/advisories/GHSA-w4x6-hh3x-wjrx (GitHub-reviewed advisory GHSA-w4x6-hh3x-wjrx lists affected ranges: NuGet gsemac.net >=0 <0.38.2)

Commands are suggestions: review each one before running it.
