Upgrade github.com/getkin/kin-openapi/openapi3filter to version 0.143.0 or higher.
Overview
Affected versions of this package are vulnerable to NULL Pointer Dereference in the openapi3filter process when handling OpenAPI 3.1 schemas that declare an array type without specifying items. An attacker can cause the application to crash by sending a crafted HTTP request with a non-empty application/x-www-form-urlencoded or multipart/form-data body, or by triggering response validation with an array-typed response header. This is only exploitable if the application uses OpenAPI 3.1 documents with array properties missing items and does not implement per-request panic recovery.
