CVE-2026-33117

The Java Key Vault Keys library in the Azure SDK for Java contains an issue in the local cryptographic verification path where authentication tag comparison was implemented incorrectly. In affected applications that use the vulnerable local cryptography path, specially crafted encrypted input may bypass integrity verification checks. Operations delegated to the Key Vault service are not affected. The issue is addressed in version 4.10.6.
