SCA: security update for Microsoft.OpenApi.Kiota (GHSA-p5rm-jg5c-8c77)

medium Tenable Self-Hosted Container Security Plugin ID 445237

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 1.34.0, an attacker who controls
 or tampers with the OpenAPI description consumed by Kiota can supply a file reference that resolves
 outside the manifest package (e.g. ../../../../etc/passwd, an absolute path, or a file:// / http(s)://
 URI). When the generated manifest is deployed and consumed by an AI host, this can lead to inclusion or
 disclosure of files outside the intended package boundary. This vulnerability is fixed in 1.29.1 and
 1.34.0. (CVE-2026-73851)

Solution

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