From 17bc42aa8d566a1f24ea28afc7fb6e5163e30a15 Mon Sep 17 00:00:00 2001 From: Dave Shanley Date: Mon, 29 Dec 2025 13:26:55 -0500 Subject: [PATCH 01/29] added new strict module MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit provides a new ‘strict mode’ engine for the validator. This is a community requested feature that will scan for undisclosed properties (noise vs signal). Anything that is submitted in a schema that is not explicitly defined (regardless of additionalProperties) will be reported. --- strict/array_validator.go | 107 ++++ strict/headers.go | 35 + strict/matcher.go | 124 ++++ strict/polymorphic.go | 475 ++++++++++++++ strict/property_collector.go | 172 +++++ strict/schema_walker.go | 234 +++++++ strict/types.go | 364 +++++++++++ strict/utils.go | 164 +++++ strict/validator.go | 247 +++++++ strict/validator_test.go | 1167 ++++++++++++++++++++++++++++++++++ 10 files changed, 3089 insertions(+) create mode 100644 strict/array_validator.go create mode 100644 strict/headers.go create mode 100644 strict/matcher.go create mode 100644 strict/polymorphic.go create mode 100644 strict/property_collector.go create mode 100644 strict/schema_walker.go create mode 100644 strict/types.go create mode 100644 strict/utils.go create mode 100644 strict/validator.go create mode 100644 strict/validator_test.go diff --git a/strict/array_validator.go b/strict/array_validator.go new file mode 100644 index 0000000..0660530 --- /dev/null +++ b/strict/array_validator.go @@ -0,0 +1,107 @@ +// Copyright 2023-2025 Princess Beef Heavy Industries, LLC / Dave Shanley +// SPDX-License-Identifier: MIT + +package strict + +import ( + "strconv" + + "github.com/pb33f/libopenapi/datamodel/high/base" +) + +// validateArray checks an array value against a schema for undeclared properties +// within array items.

This was wrong - ALL schemes in an AND requirement must pass. Refactored ValidateSecurityWithPathItem to: 1. For each security requirement (OR'd): check ALL schemes within it (AND'd) 2. Only pass if an entire requirement (all its schemes) passes 3. Try next requirement if current one fails This also fixed incorrect behavior where specs with security alternatives like api_key OR oauth2 would fail even when OAuth2 (unvalidated, so considered "passed") should satisfy the requirement. Tests and examples were updated to reflect correct behavior. --- parameters/validate_security.go | 249 +++++++++++++++------------ parameters/validate_security_test.go | 249 +++++++++++++++++++++++++++ validator_examples_test.go | 5 +- validator_test.go | 13 +- 4 files changed, 398 insertions(+), 118 deletions(-) diff --git a/parameters/validate_security.go b/parameters/validate_security.go index 8135f74..e9ca9cc 100644 --- a/parameters/validate_security.go +++ b/parameters/validate_security.go @@ -8,9 +8,9 @@ import ( "net/http" "strings" -
