SCA: security update for Microsoft.OpenApi.Kiota, Microsoft.OpenApi.Kiota.Builder (GHSA-4jwf-m4wg-8p66)

critical Tenable Self-Hosted Container Security Plugin ID 445240

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 plugin add` and `kiota
 plugin generate` (with `-t APIPlugin`) emitted attacker-controlled static_template.file values from x-ai-
 adaptive-card and x-ai-capabilities into generated Microsoft 365 Copilot and Teams plugin manifests
 without path validation, allowing ../, absolute, rooted, UNC, Windows drive, or URI paths in
 response_semantics.static_template.file to cause path traversal or out-of-package file inclusion when the
 generated plugin was deployed. This issue is fixed in version 1.32.5. (CVE-2026-59864)

Solution

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