file system operations fread

Why It Shows Up

Plugin Check found functions such as `fopen`, `fwrite`, `chmod`, `mkdir`, `readfile`, or related operations.

Why It Matters

WordPress sites can use different filesystem permissions and transports. Raw filesystem calls can fail on common hosts or write to unsafe locations.

How to Fix

• Use WordPress filesystem helpers when writing, reading, or changing files in plugin-managed paths.
• Validate paths and keep writes inside directories owned by the plugin or WordPress uploads.
• Never write PHP code from user input or remote responses.
