CVE-2025-27920 is an improper path validation vulnerability in Srimax Output Messenger before version 2.0.63, including version 2.0.62. An authenticated attacker can manipulate file-path parameters with directory-traversal sequences to access files outside their intended directories. The flaw can expose configuration files, sensitive user data, or source code, and can be leveraged to upload malicious files into the server startup directory, enabling arbitrary file execution and potentially remote code execution.
