Upgrade Microsoft.OpenApi.Kiota to version 1.32.5 or higher.
Overview
Affected versions of this package are vulnerable to Arbitrary Code Injection via the OpenApiKiotaExtension handling in LanguageInformation and kiota info output. An attacker can make a developer run attacker-controlled shell commands by supplying an OpenAPI document whose x-ms-kiota-info extension sets dependencyInstallCommand, which kiota info reads and presents as the recommended install command. The injected command is surfaced in both the human-readable kiota info guidance and the JSON output consumed by the Kiota VS Code extension, so a user who follows the install instruction or triggers dependency installation in the IDE executes arbitrary code on their workstation or CI host.
