Hi,

The following vulnerability was published for golang-github-getkin-kin-openapi.

CVE-2026-73502[0]:
| 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.
