4.9.1 (2026-09-02)

Bugs Fixed

• Fixed an issue in the challenge-based authentication policy where a cached authentication challenge, and the access token acquired for it, could be reused for a request to a different Key Vault or Managed HSM endpoint. The policy now resolves the challenge per request endpoint, ensuring a token acquired for one vault is never attached to a request to another.
