CVE-2026-92252— Incorrect Default Permissions in WatchDog Anti-Virus Installation Directory

Quick assessment

Affected
WatchDog Anti-Virus
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

WatchDog 杀毒软件在 Windows 系统上的安装目录存在不正确的默认权限配置。安装程序授予“Users”（用户）组对目录 的“完全控制”权限，这使得本地低权限用户能够修改、替换或删除杀毒软件的二进制文件及配置文件。如果这些被篡改的二进制文件随后被以更高权限运行的 WatchDog 进程加载，则可能导致防病毒保护失效，甚至引发特权代码执行漏洞。

Vulnerability Title
Incorrect Default Permissions in WatchDog Anti-Virus Installation Directory
Source: CVE Program / CVE List V5
Vulnerability Description
Incorrect default permissions in the installation directory of WatchDog Anti-Virus on Windows allow local, low-privileged users to modify, replace, or delete antivirus binaries and configuration files, because the installer grants the Users group Full Control over C:\Program Files (x86)\Watchdog Anti-Virus. This may disable antivirus protection or enable privileged code execution if modified binaries are loaded by an elevated WatchDog process.
