User-assisted spoofing
Published Aug 13, 2024 · Updated Jul 10, 2025
Spoofing in Microsoft App Installer before 1.22.11261.0 allows attackers to cause an unspecified impact via unspecified vectors. Microsoft has not published the affected code locus or the improper output encoding or escaping operation that produces the spoofed content. Exploitation requires local access to an attack path and user interaction, while the vendor has not described the resulting data or service consequence.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=1.0.0.0 <1.22.11261.0
