Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 30.6th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).
Deeper analysis
CVE-2025-68924 is a remote code execution vulnerability in Umbraco UmbracoForms through version 8.13.16. An authenticated attacker can supply a malicious WSDL (Webservice) URL as a data source to trigger the issue. The vulnerability is classified under CWE-829 and carries a CVSS v3.1 base score of 7.5 (AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H).
The attack requires low privileges (an authenticated user) and can be carried out over the network, though it demands high attack complexity and no user interaction. Successful exploitation allows the attacker to achieve high impacts on confidentiality, integrity, and availability through remote code execution on the affected system.
Mitigation details are available in related advisories and resources, including the GitHub Security Advisory at https://github.com/advisories/GHSA-vrgw-pc9c-qrrc, the Umbraco Forms package documentation at https://our.umbraco.com/packages/developer-tools/umbraco-forms/, and the NuGet package page at https://www.nuget.org/packages/UmbracoForms.

Mitigating Controls (NIST 800-53 r5) AI
Requires timely remediation of the specific flaw in UmbracoForms that allows authenticated attackers to supply malicious WSDL URLs for RCE.
Enforces validation of user-supplied WSDL URLs as data sources to block malicious inputs leading to remote code execution.
Restricts data source configuration capabilities to least privilege, limiting low-privileged authenticated users from exploiting the WSDL vulnerability.
