CVE-2026-88142

Summary

A use-after-free vulnerability in Windows BITS allows unauthenticated remote code execution, where an attacker can execute arbitrary code on a target system by exploiting a freed memory object that's still being accessed. This represents a significant security risk as it enables attackers to gain full control of affected systems without needing authentication.

Exploitability

Exploitation requires a network-based attack with minimal preconditions, as the vulnerability is accessible over the network without requiring user interaction or authentication.

Blast radius

The impact could be widespread across Windows environments that have BITS enabled, potentially allowing attackers to compromise entire networks through lateral movement and privilege escalation.

Detection

No reliable host or network indicator is derivable from the published description.

Prioritized remediation

Deploy the Windows update KB5049682 or later to address this vulnerability in the Background Intelligent Transfer Service.
