SCA: security update for github.com/getkin/kin-openapi (GHSA-h4r5-mxv5-8mjc)

medium Tenable Cloud Security Plugin ID 474717

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 0.145.0 until 0.146.0, openapi3filter
 repeatedly calls regexp.MustCompile for the same parameter-name regular expression inside the per-query-
 key loop in urlValuesDecoder.DecodeObject used to decode a deepObject query parameter. An unauthenticated
 remote client can send an affected endpoint a request containing many unrelated query keys, causing
 ValidateRequest to perform work and allocations proportional to the attacker-controlled key count for
 every deepObject parameter. The expression itself is fixed and this is not regular expression denial of
 service; the resource consumption comes from loop-invariant recompilation. This issue is fixed in version
 0.146.0. (CVE-2026-100350)

Solution

Update the github.com/getkin/kin-openapi library and its related packages to version 0.146.0 or later.
