SCA: security update for Microsoft.OpenApi.Kiota, Microsoft.OpenApi.Kiota.Builder (GHSA-hq9q-27g5-qwpj)

critical Tenable Self-Hosted Container Security Plugin ID 445239

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 1.32.5, `kiota info` read x-ms-kiota-
info.languagesInformation.<language>.dependencyInstallCommand plus dependency name and version values from
an OpenAPI description and presented the spec-supplied command as Kiota's recommended install command,
allowing an attacker-controlled or compromised description to cause command injection when the suggested
command was run manually or through the Kiota VS Code extension's kiota info --json dependency-install
flow. This issue is fixed in version 1.32.5. (CVE-2026-59865)

Solution

Update the Microsoft.OpenApi.Kiota library and its related packages to version 1.32.5 or later.
