SCA: security update for github.com/getkin/kin-openapi (GHSA-g8cf-rcjf-c8cf)

high Tenable Cloud Security Plugin ID 474677

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 0.149.0, runtime request, response, and
 direct schema validation lacks cycle detection when an allOf, anyOf, or oneOf chain refers back to an
 ancestor schema, even though loading and document validation accept the circular reference. A request or
 response that reaches the affected schema causes unbounded recursion in Schema.visitJSON or
 openapi3filter.decodeValue and exhausts the Go goroutine stack. The resulting fatal stack overflow cannot
 be caught with recover and terminates the entire process, including unrelated requests. This issue is
 fixed in version 0.149.0. (CVE-2026-100354)

Solution

Update the github.com/getkin/kin-openapi library and its related packages to version 0.149.0 or later.
