WordPress.WP.AlternativeFunctions.file_system_operations_fclose

file system operations fclose

The plugin performs filesystem work with raw PHP functions where WordPress expects safer filesystem handling.

medium weight

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.
