SCA: security update for github.com/getkin/kin-openapi (GHSA-jpcw-4wr7-c3vq)

medium Tenable Cloud Security Plugin ID 445901

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 0.2.0 until 0.144.0,
openapi3filter.ValidateRequest can encounter a NULL-pointer-dereference denial of service when an
operation declares a content parameter whose application/json media type has no schema. In
openapi3filter/req_resp_decoder.go, the default defaultContentParameterDecoder dereferences
mt.Schema.Value without checking whether mt.Schema is nil, even though doc.Validate() accepts the document
under OpenAPI 3.0.x and 3.1.x. A single unauthenticated request supplying the parameter value can panic
request validation, causing an aborted request with log growth in the common synchronous net/http path or
a full process crash in integrations without recovery. This issue is fixed in version 0.144.0.
(CVE-2026-73502)

Solution

Update the github.com/getkin/kin-openapi library and its related packages to version 0.144.0 or later.
