Pinned Microsoft.Identity.Client at 4.90.1.

Release notes

Sourced from Microsoft.Identity.Client's releases.

4.90.1

New Features

  • Added IMsalWsTrustHttpClientFactory, allowing custom HTTP client factories to provide redirect-disabled, credential-policy-aware clients for federation metadata (MEX) and WS-Trust requests. Added MsalError.TooManyRedirects and MsalError.WsTrustCrossOriginRedirectNotSupported for redirect failures. #​6165

Bug Fixes

  • Hardened federation metadata and WS-Trust requests by requiring HTTPS, securely validating redirects, rejecting credential-bearing cross-origin redirects, and limiting redirect chains. #​6165
  • Fixed instance discovery so a custom authority port is not forwarded to the global discovery host, while preserving the port when discovery uses the authority host. #​6155
  • Fixed KeyGuard attestation to send the tenant ID as the MAA client_id metadata value without changing managed-identity client-ID handling or attestation-cache partitioning. #​6200

Changes

  • Updated Microsoft.Azure.Security.KeyGuardAttestation from version 1.1.7 to 1.1.8. #​6202

4.90.0

Changes

  • Updated the KeyGuardAttestation package version to 1.1.7. #​6189

4.89.0

What's Changed

New Contributors

Full Changelog: AzureAD/microsoft-authentication-library-for-dotnet@4.88.0...4.89.0

4.88.0

New Features

  • Added user-assigned managed identity support for Azure Arc, including selecting the identity by client ID and validating the identity returned in the token response. #​6128
  • Added WithRequestOverMtls() to managed identity token requests, enabling attested bearer-token acquisition over the IMDSv2 mTLS transport. #​6086

Bug Fixes

  • Fixed token-cache key collisions by length-prefixing additional cache-key components before hashing. #​6137
  • Populated authentication-result telemetry metadata on proactive background-refresh results. #​6157
  • Fixed mTLS PoP authority validation incorrectly rejecting sovereign-cloud aliases such as login.chinacloudapi.cn and login.usgovcloudapi.net. #​6153

4.87.0

What's Changed

  • Expose MsalServiceException.ErrorCodesForLogging for diagnostics in #​6138
  • Expose WithOtelTagsEnricher for managed identity requests in #​6144
  • Forward OpenTelemetry tags enricher to the client-assertion callback in #​6142
  • Add client-side opaque-token log scrubber in #​6119
  • Populate ExecutionResult.Exception for non-MSAL failures in #​6139
  • Use PSS padding in KeyGuard liveness probe (CodeQL SM03799) in #​6141
  • Remove managed identity support from WithClaimsFromClient (confidential-client only) in #​6113
  • Remove experimental features from client setup in #​6143
  • Update Azure Arc managed identity API version from 2019-11-01 to 2020-06-01 in #​6130

Full Changelog: AzureAD/microsoft-authentication-library-for-dotnet@4.86.1...4.87.0

4.86.1

Bug Fixes

  • Fixed the mTLS Proof-of-Possession token cache to key on the certificate's full DER (x5t#S256) instead of only the public key, preventing a stale token (and AADSTS500181) after a same-key certificate renewal. #​6123
  • Fell back to RS256 when a certificate's PSS signing operation is rejected by RSACryptoServiceProvider, rebuilding the client assertion so authentication can proceed. #​6126
  • Detect and reject symbolic links in the Unix cache-file write path (lstat pre-check plus O_NOFOLLOW), closing a TOCTOU window. #​6115
  • Corrected misleading "region required" error messages and doc comments in the mTLS PoP flow. #​6127

4.84.2

New Features

  • Added ManagedIdentityApplication.GetManagedIdentityCapabilitiesAsync(CancellationToken) returning a ManagedIdentityCapabilities object that reports the detected managed identity Source, the host's MaxSupportedBindingStrength (new MtlsBindingStrength enum: None, Software, KeyGuard), and a derived IsMtlsPopSupportedByHost. Replaces GetManagedIdentitySourceAsync()/ManagedIdentitySourceResult. The public ManagedIdentitySource.ImdsV2 value is folded into Imds (v1/v2 routing remains internal). #​6049
  • Added OID-based user identification to the User Federated Identity Credential (user_fic) flow via AcquireTokenByUserFederatedIdentityCredential(scopes, Guid userObjectId, assertion). #​6050
  • Added WithClaimsFromClient(claimsJson) to forward client-originated claims across managed identity and confidential client flows. #​5999
  • Added mTLS PoP support for WithCertificate(() => x509) (dynamic certificate credential). #​5957
  • Added opt-in token-acquisition metrics covering both successful and failed attempts. #​6004

Changes

  • Extended mTLS bearer transport (CertificateOptions.SendCertificateOverMtls) to the OBO, refresh-token, and authorization-code flows. #​6009
  • General Availability of the Microsoft.Identity.Client.KeyAttestation package. #​6038
  • Managed identity now probes IMDSv2 first and the preview latch was removed. #​6041
  • Updated NativeInterop baseline and corrected devapp version ranges. #​6045
  • Simplified GetTenantedAuthority in CiamAuthority and DstsAuthority. #​6001

Bug Fixes

  • Fixed WithExtraQueryParameters on ManagedIdentityApplicationBuilder bypassing token caching. #​6035
  • Guarded HTTP status codes on discovery endpoints in KnownInstanceMetadataIsUpToDateAsync. #​6048
  • Detect orphaned KeyGuard certificates via public-key modulus comparison. #​6020

4.84.1

What's Changed

New Features

  • Added WithReservedScopes and WithCachePartitionKey public API extensions in #​6014
  • Added IAuthenticationOperation3 interface for CDT + mTLS PoP composition in #​5996
  • Added MsalRemainingTokenLifetime histogram metric for token expiry tracking in #​5920

Changes

  • Removed [Obsolete] attribute from WithExtraBodyParameters extension method in #​6006
  • Replaced ConcurrentHashSet with ConcurrentDictionary<T, byte> in #​5975

Bug Fixes

  • Fixed WithTenantId not honoring MSA tenant GUID when specified at request level in #​5958
  • Fixed OBO cache returning multiple_matching_tokens_detected when attributed tokens share a partition in #​5993

Looks like this PR has been edited by someone other than Dependabot. That means Dependabot can't rebase it - sorry!

If you're happy for Dependabot to recreate it from scratch, overwriting any edits, you can request @dependabot recreate.

Looks like Microsoft.Identity.Client is no longer a dependency, so this is no longer needed.
