SCA: security update for github.com/getkin/kin-openapi (GHSA-mmfr-pmjx-hw9w)

high Tenable Cloud Security Plugin ID 446237

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. From 0.10.0 until 0.141.0,
 openapi3filter.convertParseError in openapi3filter/validation_error_encoder.go dereferences e.Parameter.In
 without checking whether e.Parameter is nil. A malformed non-string scalar field in a multipart/form-data
 request body produces a nested ParseError with a nil RequestError.Parameter, and applications that render
 the validation error through openapi3filter.ConvertErrors or ValidationErrorEncoder panic. An
 unauthenticated client can repeatedly send such requests to deny service when the application lacks a
 recovery boundary. JSON request bodies and applications that do not use these error-rendering helpers are
 not affected. This issue is fixed in version 0.141.0. (CVE-2026-76905)

Solution

Update the github.com/getkin/kin-openapi library and its related packages to version 0.141.0 or later.
