Administrator-level file read via unchecked log path
Published Oct 11, 2025 · Updated Oct 11, 2025
Path traversal in BestWebSoft Error Log Viewer 1.1.6 and earlier allows remote authenticated users to read arbitrary server files. The rrrlgvwr_get_file function accepts a request-selected path containing traversal sequences and reads the target without confining it to an approved log directory. Administrator-level WordPress access is required, and successful exploitation exposes readable server files without reported modification or service interruption.
