Command Injection Information Disclosure in Microsoft Copilot

Successful exploitation allows an unauthenticated remote attacker to obtain information from the affected Copilot environment over the network. Based on the provided content, the demonstrated impact is information disclosure rather than code execution or privilege escalation. The broader Patch Tuesday reporting also associates Copilot fixes with preventing misleading or spoofed content in the assistant interface, but for CVE-2025-59252 specifically, the supplied description supports information disclosure via command injection.

If immediate patching is not possible, reduce exposure by limiting unauthenticated network access to affected Copilot services, restricting external access paths where feasible, and monitoring for anomalous requests or responses that may indicate command-injection attempts or unexpected data disclosure. Because the provided content does not include vendor-specific workaround guidance, definitive mitigations beyond patching are currently not available.

Apply the Microsoft security update that addresses CVE-2025-59252 in Copilot as part of the October 2025 Patch Tuesday release. No more specific product-version remediation details are provided in the supplied content.
