• CVE-2025-68924: 0.76% estimated exploitation activity in the next 30 days; percentile 55.17 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Impact Within Umbraco Forms, configuring a malicious URL on the Webservice data source can result in Remote Code Execution. This affects all Umbraco Forms versions running on .NET Framework (up to and including version 8). Patches The affected Umbraco Forms versions are all End-of-Life (EOL) and not supported anymore, hence no patches will be released. Upgrading to any of the currently supported versions (v13, v16 or v17) is recommended. Workarounds If none of the configured Forms data sources uses the Webservice type, it can be safely excluded by adding the following code to the application. This will completely remove the option to select/use this data source within the Backoffice and thereby mitigate the vulnerability. Any Webservice data source that is configured and still in use should be replaced with a custom implementation instead, before applying the above code. If this is not feasible, the vulnerability can be minimized by revoking the 'Manage Data Sources' from any…

# Patch Next advisory brief: CVE-2025-68924

Advisory: UmbracoForms Vulnerable to Remote Code Execution via Untrusted WSDL Compilation in Dynamic SOAP Client Generation
IDs: CVE-2025-68924, GHSA-vrgw-pc9c-qrrc
Record: https://patchnext.com/advisories/cve-2025-68924 (revision 1, source checked 26 Oct 2026, 17:04 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Critical (CVSS 9.9)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor response not established. A vendor fix does not mean a deployment is fixed.

## Affected components
- NuGet umbracoforms: affected <= 8.13.16

## Suggested inspection (read-only)
- NuGet umbracoforms: check the installed version with your package manager.

## 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 umbracoforms.
- 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-vrgw-pc9c-qrrc (GitHub-reviewed advisory GHSA-vrgw-pc9c-qrrc lists affected ranges: NuGet umbracoforms >=0 <=8.13.16)
