CVE-2026-32191 is a critical remote code execution vulnerability in Microsoft Bing Images caused by improper neutralization of special elements used in an operating system command. The vulnerable path is described as a server-side image ingestion route in which Bing fetches an attacker-supplied remote image URL and passes the retrieved content into a backend image-processing pipeline. Available reporting indicates that crafted SVG content could reach a delegate-capable image conversion component compatible with ImageMagick-style processing, where attacker-controlled input was interpreted in a way that resulted in shell command execution during parsing or rasterization. The issue is remotely reachable over the network, requires no authentication or user interaction, and affects Microsoft-managed hosted service infrastructure rather than customer-managed deployments.
