Deeper analysis
Microsoft Edge (Chromium-based) Webview2 contains a spoofing vulnerability tracked as CVE-2023-24892. The flaw received a CVSS 3.1 score of 8.2 and is associated with CWE-601 and CWE-290, indicating issues with URL redirection and authentication spoofing. It affects the Webview2 component used by applications embedding the Edge browser engine.
An unauthenticated remote attacker can exploit the vulnerability over the network with low complexity by crafting content that triggers user interaction. Successful exploitation allows the attacker to spoof interface elements or redirect navigation, resulting in high confidentiality impact and limited integrity changes within the affected context.
Microsoft published advisory details for CVE-2023-24892 on its Security Response Center site at https://msrc.microsoft.com/update-guide/vulnerability/CVE-2023-24892. The current and peak EPSS scores both stand at 0.1704 with no material increase observed after disclosure.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Training specifically addresses recognizing spoofed communications and phishing that enable authentication bypass.
Reveals spoofed logon attempts through unexpected previous logon timestamps upon legitimate login.
Requiring verifiable identity evidence at appropriate assurance levels makes it substantially harder for attackers to successfully spoof or impersonate users to obtain accounts.
Unique device authentication makes successful spoofing of device identity substantially more difficult to achieve.
Unique identification of non-organizational users reduces the feasibility of authentication bypass by spoofing.
Unique identification and authentication of services before communications makes spoofing of service identities substantially harder.
Isolated trusted path ensures the user interacts only with genuine system components, preventing spoofing of authentication interfaces or prompts.
Directly counters DNS response spoofing by requiring cryptographic origin authentication artifacts from the authoritative source.
