SCA: security update for github.com/getkin/kin-openapi (GHSA-mh7x-f8wq-4jhx)

medium Tenable Cloud Security Plugin ID 474718

Description

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

 - kin-openapi is a Go project for handling OpenAPI files. Prior to 0.145.0, openapi3.Loader can dereference
 a nil SchemaRef.Value while resolving a self-referential additionalProperties JSON Reference such as a
 schema that points to its own additionalProperties member. Loading an attacker-controlled OpenAPI document
 through LoadFromData, LoadFromFile, or LoadFromURI reaches resolveComponent before document validation and
 can panic the loading process. Resolved additionalProperties schemas and ordinary recursive schemas do not
 take the vulnerable nil-value path. This issue is fixed in version 0.145.0. (CVE-2026-100348)

Solution

Update the github.com/getkin/kin-openapi library and its related packages to version 0.145.0 or later.
