high Tenable Self-Hosted Container Security Plugin ID 445293

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 1.32.3, Kiota is affected by a code-
generation injection vulnerability in the C# XML documentation-comment sink (the description, externalDocs
label, and externalDocs link fields emitted as /// … comments). When text from an OpenAPI description is
written into single-line XML doc comments without stripping newline and Unicode line-terminator
characters, an attacker can break out of the /// comment line and inject additional code into generated C#
clients. This issue is fixed in version 1.32.3. (CVE-2026-59860)

Solution

Update the Microsoft.OpenApi.Kiota library and its related packages to version 1.32.3 or later.
