SCA: security update for github.com/getkin/kin-openapi (GHSA-23vg-4cjm-66q5)

high Tenable Cloud Security Plugin ID 474703

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 0.144.0 until 0.147.0,
openapi3filter.ValidationHandler validates an operation selected from decoded URL.Path while a downstream
gorilla/mux router configured with UseEncodedPath can dispatch a different operation selected from
URL.RawPath. When a public exact route and a protected parameterized route use the same method and overlap
after decoding, an unauthenticated remote request containing an encoded path separator can be validated as
public and then dispatched to the protected handler without invoking the configured AuthenticationFunc.
The reachable path parameter is constrained to an encoded representation that decodes to the public
literal route, and proxies that canonicalize the URI before forwarding prevent this specific mismatch.
This issue is fixed in version 0.147.0. (CVE-2026-100351)

Solution

Update the github.com/getkin/kin-openapi library and its related packages to version 0.147.0 or later.
