high Tenable Cloud Security Plugin ID 445271

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Kiota is an OpenAPI based HTTP Client code generator. Prior to 1.29.1 and 1.32.5, Kiota resolved OpenAPI
 $ref values by fetching remote http(s) URLs and reading local absolute or out-of-tree file paths, allowing
 `kiota generate` on an attacker-controlled or attacker-influenced description to perform build-time SSRF,
 remote file inclusion, and local file inclusion by inlining external schemas such as REMOTE_KIOTA_PROP or
 Leaked into generated clients. This issue is fixed in version 1.29.1 and 1.32.5 by
 AllowedExternalOriginsStreamLoader and the --allowed-external-origins option. (CVE-2026-59867)

Solution

Update the Microsoft.OpenApi.Kiota library and its related packages to version 1.29.1 or later.
