Updated Microsoft.Identity.Client.Extensions.Msal from 4.86.0 to 4.86.1.

Release notes

Sourced from Microsoft.Identity.Client.Extensions.Msal's releases.

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
