CVE-2026-32191 is a critical remote code execution vulnerability in Microsoft Bing Images. The issue is described by Microsoft and NVD as improper neutralization of special elements used in an operating system command, i.e., an OS command injection flaw. A network-accessible Bing Images service component processes attacker-controlled input in a way that can cause unintended OS command execution. Publicly available sources do not disclose the specific vulnerable function, endpoint, or internal component, but the weakness class and impact are established: an unauthorized attacker can exploit the flaw remotely to execute code within Microsoft’s hosted Bing Images environment.
