Zero-Day Vulnerability CVE-2026-15682 in AnyDesk Enables Denial-of-Service Attacks on Affected Systems

A newly disclosed zero-day vulnerability in AnyDesk, tracked as CVE-2026-15682, allows attackers to trigger denial-of-service conditions on systems running the popular remote access tool. The flaw centers on a support information transmission feature that can be abused through Windows file system redirection mechanisms. An attacker with limited local access can manipulate these redirections to crash either the AnyDesk application or the underlying operating system. Because AnyDesk is widely deployed by support teams, managed service providers, and internal IT departments, the vulnerability poses a significant risk to remote assistance workflows and incident response operations. Until an official patch is released, organizations are advised to restrict code execution privileges, monitor for anomalous file system redirection activity, and apply updates as soon as they become available.
