CVE-2026-15681

AnyDesk Screen Recording Link Following Denial-of-Service Vulnerability

Published Jul 13, 2026 CVSS 3.1 · 5.5 Medium EPSS < 1% KEV · Not listed

Description

AnyDesk Screen Recording Link Following Denial-of-Service Vulnerability. This vulnerability allows local attackers to create a denial-of-service condition on affected installations of AnyDesk. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.

The specific flaw exists within the handling of screen recording files. By creating a junction, an attacker can abuse the service to create arbitrary files. An attacker can leverage this vulnerability to create a denial-of-service condition on the system. Was ZDI-CAN-26591.

Analysis

Technical impact

The flaw allows a local attacker who has obtained low‑privilege code execution to craft a junction that manipulates screen recording file handling, enabling the creation of arbitrary files. This leads to a denial‑of‑service condition on the affected AnyDesk installation. The weakness is a path manipulation issue (CWE‑59).

Affected Systems

AnyDesk – The AnyDesk 9.0.4 client is vulnerable to this flaw. This version is identified directly in the CNA CPE string. Users running AnyDesk 9.0.4 on any platform are potentially impacted until a patch is applied.

Risk and Exploitability

The CVSS score of 5.5 indicates medium severity but the vulnerability requires low‑privilege code execution. EPSS is < 1% and the vulnerability is not listed in KEV, suggesting it is not a known, actively exploited flaw. The local exploit vector means that privileged users or malware that has achieved code execution on the host can trigger the denial‑of‑service behavior.

Affected Products

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).

OpenCVE Recommended Actions

Apply the latest AnyDesk security update to eliminate the screen recording handling flaw.
Restrict local user privileges to prevent arbitrary code execution that could create malicious junctions.
Disable or revoke permissions for the AnyDesk screen recording feature if it is not required.
Monitor the system for unexpected file creation in the AnyDesk directory and review junction usage logs.
