WordPress.WP.AlternativeFunctions.file_system_operations_chmod
file system operations chmod
The plugin performs filesystem work with raw PHP functions where WordPress expects safer filesystem handling.
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.
