📝 WalkthroughWalkthroughNetwork security access control now covers outbound URLs and remote OpenAPI, WSDL, and schema references. Platform and tenant policies configure parser and resolver behavior. REST flows report blocked URLs as client validation errors. ChangesNetwork security access control
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟠 High · up to The change adds outbound host controls, but WSDL URL processing still probes or fetches the root URL before validation. This can bypass the configured policy and permit requests to disallowed or private hosts, so the PR is not safe to merge until the root URL is gated before any network access.

Pull request overview
This PR introduces a configurable network access-control policy to constrain outbound fetches performed while importing/validating APIs and related artifacts (OpenAPI remote $refs, WSDL imports/includes, endpoint URL validation, and URL-based import flows such as Key Manager and Service Catalog), enabling operators/tenants to prevent SSRF-style resolution to untrusted or private/loopback targets.
Changes:
- Adds platform + tenant configuration surfaces for network access control (template + tenant config schema), and new
ExceptionCodesfor untrusted URLs (endpoint vs embedded-in-definition). - Wires URL gating into key outbound paths: OpenAPI parsing/ref resolution (incl. archives), WSDL 1.1 schema import resolution (locator/fetcher), WSDL 2.0 URI resolver, and multiple REST API entry points for endpoint/definition URLs.
- Adds extensive unit/regression tests and fixtures covering blocked refs, archive behavior, WSDL gating/resolution, and parser option propagation.

path using new URL(url).openConnection() or url.openStream() to reuse the IP
address resolved and approved during validation. Ensure the connection cannot
perform a fresh DNS lookup after policy checks, while preserving the original

- Around line 509-535: Update getBasedXSDofWSDL to classify schemaUrl before
network validation and remote fetching; for non-HTTP(S) namespace-derived URLs
such as urn values, return null so the existing local/base-XSD fallback remains

each endpointArray element before treating it as a JSON object, avoiding
unchecked JSONException for primitive or otherwise malformed values. Preserve
adding only nonblank API_DATA_URL values, and ensure malformed elements are
skipped or handled through the existing client-error path rather than
propagating a 500.
- Around line 12503-12513: Update validateRemoteURL to accept parameterized
endpoint templates containing { } consistently with validateEndpointURL. Ensure
host extraction uses the existing template-aware exclusions or tolerant parsing
so valid parameterized URLs are not rejected as malformed, while preserving

- Around line 255-268: The parameterized-URL exemption in
APIUtil.validateRemoteURL is too broad because it skips validation for URLs with
static hosts and templated paths. Restrict the bypass to unresolved
authority/host templates and non-HTTP endpoint schemes, while continuing normal
policy and private-network validation for HTTP(S) URLs with concrete hosts.
Update testValidateRemoteURLSkipsParameterizedEndpointWhenPolicyEnabled and add
coverage asserting a denied static host with a parameterized path is rejected.

- Around line 2758-2771: Update extractURLsFromEndpointConfig and its parent
validation flow so an endpoint array containing no usable URL entries returns
the endpoint-specific ENDPOINT_URL_NOT_PROVIDED error, including the sandbox or
production endpoint type, instead of falling through to INVALID_ENDPOINT_URL.
Preserve successful extraction for mixed arrays containing valid entries, and
add a regression case covering arrays composed only of malformed or non-object
entries.

`@components/apimgt/org.wso2.carbon.apimgt.spec.parser/src/main/java/org/wso2/carbon/apimgt/spec/parser/definitions/OASParserUtil.java`:
- Around line 1028-1030: Update the parser resolution flow around OASParserUtil
and gateArchiveRemoteRefs so configured platform-and-tenant network policy is
enforced for every transitive remote $ref fetched by OpenAPIV3Parser.read().
Pass the applicable OASParserOptions into ParseOptions for both OAS 3 and
Swagger 2.0 parser paths, while preserving local archive containment and
existing handling of local or relative refs.

…s-control policy Route embedded remote $ref resolution for OpenAPI 2.0 and 3.x definitions through the network access-control policy so references to blocked or internal hosts are rejected before any fetch, instead of being resolved unconditionally. - Enable swagger-parser's built-in safe URL resolver for OAS 2.0 and 3.x across the validate, re-parse and archive-master flows when a policy is configured; no-op otherwise for backwards compatibility. - Add OASParserOptions plus an APIUtil helper to build the allow/block lists and the policy-enabled flag from the platform/tenant configuration. - Add the UNTRUSTED_URL_IN_DEFINITION error code and surface a blocked reference as an HTTP 400 with a neutral message from the API, MCP-server and service-catalog entry points. - Cover OAS 2.0/3.x inline, URL and archive definitions, including nested references, with tests.
…he network access-control policy Route nested WSDL/schema references (xsd:import/include/redefine, wsdl:import) discovered while parsing WSDL 1.1 and 2.0 documents through the network access-control policy, so a reference to a blocked/internal host or a path escaping the uploaded archive is never fetched or read. - Add AccessControlledWSDLLocator (WSDL 1.1) and AccessControlledUriResolver (WSDL 2.0) that validate every remote reference before fetching and contain local references to the archive root, redirecting a blocked reference to a harmless empty stub so the parse degrades gracefully. - Add a policy-gated remote schema fetcher and a shared WsdlTenantResolver that falls back to the super tenant when no CarbonContext is available on the current thread. - Surface a blocked reference as an HTTP 400 with a neutral message; map genuine (non-policy) failures to CANNOT_PROCESS_WSDL_CONTENT. - Cover the remote, archive-escape, nested-subdirectory and non-reachable vectors with tests.
- Fail fast with NETWORK_SECURITY_ACCESS_CONTROL_MISCONFIGURED when a policy is enabled with an unrecognized mode; a blank mode remains valid (private-network-only), matching applyAccessControlPolicy. - Apply finite connect/read timeouts to the WSDL schema fetch so a slow remote endpoint cannot hang import processing. - Preserve the original error handler when re-wrapping exceptions in API and MCP-server import, so a blocked-reference 400 is no longer flattened into a generic 500. - Fix the WSDL blocked-reference tests to assert UNTRUSTED_URL_IN_DEFINITION (the code's actual error code) rather than UNTRUSTED_URL. - Add the missing Apache license header to the WSDL access-control test files. - Document the redirect-follow residual on the WSDL 2.0 resolver: an allow-listed host that redirects to another target is followed without re-validating the redirect target.
- updateSwagger: load the network-security policy with the Carbon tenant domain instead of the request organization, matching the other entry points - WSDL SOAP operation extractor: propagate a blocked-reference init failure instead of overriding it, and skip non-HTTP(S) (e.g. urn:) namespaces so they fall back to the local base XSD instead of failing validation - WsdlTenantResolver: fall back to the super tenant when the tenant domain is blank - Require Mode in the tenant NetworkSecurityAccessControl config and scope the private-network host exemption wording to allow mode - Cap per-file reads in the archive remote-reference scan - Remove unused imports and de-duplicate the Key Manager URL bad-request handling - Fix an ExceptionCodes javadoc link; close streams and assert the specific size-limit exception in tests; add regression tests locking the blocked-URL message fragments to the pinned parser version
- OpenAPI archive scan: reject the archive when a file exceeds the size cap instead of skipping it, so an oversized file cannot be parsed and have its remote references resolved past the policy check - buildRefResolutionOptions: combine the platform and tenant policies with AND semantics for remote-$ref resolution - union deny hosts, intersect allow hosts, remove any denied host from the allow-list (the resolver's allow-list short-circuits over the block-list), and add a wildcard deny in allow mode so allow-mode is a restrictive whitelist rather than an exemption list, with mixed-mode and precedence unit tests - WSDLSOAPOperationExtractorImplTestCase: establish a super-tenant CarbonContext in setup so namespace-derived schema validation resolves to a no-op instead of failing when the test runs without a tenant context
- OpenAPI archive: the archive is parsed with resolution enabled, so a local reference could previously escape the archive and read arbitrary local files. Reject any file: reference, absolute path, or relative path whose canonical target lies outside the extracted archive root, while leaving in-archive references untouched so multi-file archives still resolve. Containment is enforced whether or not a network access-control policy is configured; remote references remain gated by the policy when one is set. - Key Manager URL validation: skip values that are not absolute URLs (scheme + host) - such as the 'none' sentinel and relative values - instead of failing them as malformed, and map only a policy block (UNTRUSTED_URL) to the field-specific 'not trusted' message, propagating other errors (e.g. malformed URL) unchanged so the message stays accurate. - add archive traversal/file:/no-policy containment tests and Key Manager URL validation tests
…trol tests These tests replace the process-wide APIManagerConfigurationService and APIMConfigService in setup; capture the previous values and restore them in the @after teardown so later tests in the same fork do not inherit the no-op mocks.
Rename the deployment.toml key that configures outbound-request network access control from [apim.network_security.access_control] to [server.network_security.access_control], so the same configuration surface can be shared across products. Only the api-manager.xml.j2 template's key lookups change; the rendered <NetworkSecurityAccessControl> element and the configuration read path are unchanged.
- Skip parameterized (e.g. http://{uri.var.host}/x), JMS and Consul endpoint
URLs in the remote-URL check, mirroring validateEndpointURL, so legitimate
templated endpoints are not rejected as malformed when the policy is enabled.
- Guard non-object entries when extracting endpoint URLs from an endpoint
config array so a malformed config yields a client error instead of a 500.
- Honor the configured OpenAPI import size limit (falling back to the default
only when unset) for the archive path, matching the URL/inline paths.
- Use Locale.ROOT for the archive 'file:' scheme check so locale-specific
case folding cannot defeat the containment guard.
Adds unit tests for the templated-URL skip and the non-object array element.
Drop the 'Genuine' qualifier from the warn logs emitted when a nested WSDL schema reference cannot be resolved, addressing review feedback.

Add a configurable network access-control policy for outbound definition and endpoint fetches
Purpose
When API Manager resolves a user-supplied artifact — an OpenAPI/Swagger definition with remote
$refs, a WSDL with remotexsd:import/include, an endpoint URL, or a URL passed to the Key Manager and Service Catalog import flows — it may fetch content from external hosts. This change introduces a configurable network access-control policy that governs which hosts those outbound fetches are allowed to reach, so operators can constrain resolution to an approved set of hosts (or block private/loopback ranges) instead of the server fetching from arbitrary addresses.Configuration
[apim.network_security.access_control]section indeployment.toml(templated intoapi-manager.xml), withmode(allow/deny), a host list, and ablock_private_network_accesstoggle.NetworkSecurityAccessControlobject intenant-conf.json(validated against the tenant config schema) applies a tenant-level policy on top of the platform policy. The two are combined as a logical AND (defense-in-depth): a URL must pass both the platform and the tenant policy, so a tenant can further restrict outbound access but cannot relax the platform policy.The policy is off unless configured, so existing deployments are unaffected by default.
What changed
APIUtil.validateRemoteURL(url, tenantDomain)evaluates a URL against the effective policy, andAPIUtil.buildRefResolutionOptions(options, tenantDomain)threads the policy into the definition parser's reference resolver. NewExceptionCodesdistinguish an untrusted endpoint URL from an untrusted URL discovered inside a definition.$ref— remote reference resolution is gated for validate, import (inline and multi-file archive), update, and the MCP-server-from-OpenAPI flow, across OAS 2.0 / 3.0 / 3.1. Nested references are re-validated as the resolver crawls, so a reference cannot escape the policy transitively.xsd:import/includeschema fetches are gated through a policy-awareWSDLLocator/ URI resolver (AccessControlledWSDLLocator,AccessControlledUriResolver,PolicyGatedSchemaFetcher) for both WSDL 1.1 and 2.0 processing.Tests
Adds unit coverage for the parser options, the ref-resolution options builder, the WSDL locator/resolver/fetcher, archive-ref handling, and the OAS parsers — plus fixture definitions for blocked/loopback and clean references.
Notes
This branch aggregates the work reviewed and merged into the
feature_nw_access_controlbranch (the configurable host-validation base plus the$refand WSDL schema-import gating on top).upstream/masterhas been merged in; the single content conflict — inMcpServersApiServiceImpl.updateMCPServerBackend, where master added anAPI_SUBTYPE_DIRECT_BACKENDguard around the definition validation — was resolved by keeping that guard while retaining the tenant-scoped reference-resolution options on the validation call. Pairs with the corresponding UI change (wso2/apim-apps#1395).
