CVE-2024-35266Network attack vector

Authenticated content spoofing via undisclosed cross-site scripting

Published Jul 9, 2024 · Updated Dec 9, 2025

Cross-site scripting in Microsoft Azure DevOps Server 2022 allows remote authenticated users to spoof content through crafted input. Microsoft has not disclosed the affected web component or the server-side operation that fails to neutralize attacker-controlled input before page generation. Exploitation requires low-privilege access and a victim's interaction, and the resulting script can read or alter session data and cause limited service interruption.
