🚨 VULNERABILITY UPDATE

Trusting your SDK might be your biggest blind spot.

A critical RCE vulnerability, CVE-2026-21531 ("Azure SDK Ghost"), has been identified in the Azure AI Language Authoring SDK (specifically the Python library).

The flaw lies in the insecure deserialization of "continuation tokens." An unauthenticated remote attacker can supply a maliciously crafted token that, when processed by the SDK, triggers arbitrary code execution on the underlying host.

No Authentication: Attackers don't need credentials.

No Interaction: The exploit triggers automatically during standard data processing.

Microsoft released patches on Feb 10. If you are using azure-ai-language-conversations-authoring in your Python environment, update to the latest version immediately and audit your exposed endpoints.
