Summary by CodeRabbit

  • Security Enhancements
    • Improved redirect URI validation across authorization, token issuance, and pushed authorization request flows.
    • Ensures invalid redirect destinations are consistently rejected across supported OAuth and OpenID Connect endpoints.
  • Reliability
    • Standardized validation behavior to provide more consistent handling of redirect-related errors.

Review Change Stack

Walkthrough

Changes

The change converts IdentityProviderUtil from static URL-validator state to constructor-injected instance state. Authorization and OAuth services now use the injected utility. Tests update construction, mocking, and certificate generation.

Redirect Validation Wiring

Layer / File(s) Summary
Instance-based utility state and validation
esignet-core/src/main/java/io/mosip/esignet/core/util/IdentityProviderUtil.java
IdentityProviderUtil uses constructor injection. Redirect validation and URI matching are instance methods. Logging uses Lombok.
OIDC service integration
oidc-service-impl/src/main/java/io/mosip/esignet/services/AuthorizationServiceImpl.java, oidc-service-impl/src/main/java/io/mosip/esignet/services/OAuthServiceImpl.java
Authorization and OAuth flows call redirect validation through the injected utility instance.
Test and certificate updates
esignet-core/src/test/java/io/mosip/esignet/core/IdentityProviderUtilTest.java, oidc-service-impl/src/test/java/io/mosip/esignet/services/AuthorizationServiceTest.java, oidc-service-impl/src/test/java/io/mosip/esignet/services/OAuthServiceTest.java
Core tests initialize the utility with validator configuration. Service tests mock the utility. Certificate tests use Bouncy Castle builders.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Mergeability Score: 🔵 Low · up to 3e477

The PR updates redirect-URI validation handling and its tests. It is mergeable with owner awareness or a small follow-up to rename the modified JUnit methods to the repository's required convention; no concrete runtime impact is evidenced.

Poem

Static paths now take a seat,
Injected validators make flows complete.
Certificates build with a newer hand,
Tests mock the utility as planned.
Redirects pass through instance state.

Rename the changed JUnit test methods.

These methods do not follow the required should_<expectedBehavior>_when_<condition> format. Rename each changed test method.

Proposed naming pattern
- public void validateRedirectURIPositiveTest() throws EsignetException {
+ public void should_acceptRedirectUri_when_uriMatchesRegisteredPattern() throws EsignetException {

- public void test_generateSalt() {
+ public void should_generateSalt_when_requestedLengthIsValid() {

As per path instructions: All JUnit test method names must follow: should_<expectedBehavior>_when_<condition>.

Also applies to: 77-77, 121-121, 128-128, 134-134, 143-143, 152-152, 159-159, 164-164, 170-170, 308-308, 319-319

Assert redirect-validator delegation in every changed flow.

The IdentityProviderUtil mocks return successfully by default. The OAuth invalid-redirect tests fail in validateRequestParametersWithTransaction before the injected validator runs. The authorization tests configure validator failure for V1 and V2 only. Add direct delegation assertions and an invalid-redirect V3 test.

  • oidc-service-impl/src/test/java/io/mosip/esignet/services/OAuthServiceTest.java#L88-L89: Verify validateRedirectURI in successful token and PAR tests. Add a matching-transaction redirect case where the validator throws.
  • oidc-service-impl/src/test/java/io/mosip/esignet/services/AuthorizationServiceTest.java#L119-L120: Add a V3 invalid-redirect test that makes identityProviderUtil.validateRedirectURI(...) throw INVALID_REDIRECT_URI.
Proposed assertion
verify(identityProviderUtil).validateRedirectURI(
        eq(clientDetail.getRedirectUris()),
        eq(request.getRedirectUri()));
