Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

FileRun 版本 2026.3.0 之前存在 OS 命令注入漏洞，位于 PhotoProofSheet 处理器中。该漏洞允许拥有上传权限的认证用户通过上传文件名中含有 shell 元字符的文件，执行任意命令。攻击者可以上传文件名中包含命令替换语法（如反引号、分号或 $() 序列）的文件，然后触发 PhotoProofSheet 端点。由于在构造 ImageMagick montage 命令时缺少 过滤，任意命令将作为 web 服务器用户执行。

Vulnerability Title
FileRun < 2026.3.0 OS Command Injection via PhotoProofSheet Handler
Source: CVE Program / CVE List V5
Vulnerability Description
FileRun before 2026.3.0 contains an OS command injection vulnerability in the PhotoProofSheet handler that allows authenticated users with upload permission to execute arbitrary commands by uploading files with shell metacharacters in their names. Attackers can upload a file containing command substitution syntax such as backticks, semicolons, or $() sequences in the filename, then trigger the PhotoProofSheet endpoint to execute arbitrary commands as the web-server user due to missing escapeshellarg() sanitization in the ImageMagick montage command construction.
