Version 4.6.2

Release Date: July 26, 2025

4.6.2 release of CodeIgniter4

SECURITY

Changes

  • Security: The sanitize_filename() function from the Security helper now supports a second parameter to control whether relative paths are allowed.

Deprecations

  • Security: The Security::sanitizeFilename() method is deprecated. Use sanitize_filename() instead.
  • Security: The SecurityInterface::sanitizeFilename() method is deprecated.

Bugs Fixed

  • Cache: Fixed a bug where a corrupted or unreadable cache file could cause an unhandled exception in FileHandler::getItem().
  • Commands: Fixed a bug in make:test where it would always error on Windows.
  • Commands: Fixed a bug in make:test where the generated test file would not end with Test.php.
  • Commands: Fixed a bug in make:test where input prompt would display for three times after not entering a class name.
  • CURLRequest: Fixed a bug where intermediate HTTP responses were not properly removed from the response chain in certain scenarios, causing incorrect status codes and headers to be returned instead of the final response.
  • Database: Fixed a bug where when() and whenNot() in ConditionalTrait incorrectly evaluated certain falsy values (such as [], 0, 0.0, and '0') as truthy, causing callbacks to be executed unexpectedly. These methods now cast the condition to a boolean using (bool) to ensure consistent behavior with PHP's native truthiness.
  • Database: Fixed encapsulation violation in BasePreparedQuery when accessing BaseConnection::transStatus protected property.
  • DownloadResponse: Fixed a bug where filename parameters were missing from Content-Disposition headers when using inline disposition, causing browsers to use the last URL segment for filenames instead of the intended filename.
  • Email: Fixed a bug where Email::getHostname() failed to use $_SERVER['SERVER_ADDR'] when $_SERVER['SERVER_NAME'] was not set.
  • Security: Fixed a bug where the sanitize_filename() function from the Security helper would throw an error when used in CLI requests.
  • Session: Fixed a bug where using the DatabaseHandler with an unsupported database driver (such as SQLSRV, OCI8, or SQLite3) did not throw an appropriate error.
  • SiteURI: Fixed a bug in SiteURIFactory::parseRequestURI() where serving the app from a subfolder using mod_rewrite while preserving the index.php file would cause incorrect route path detection.
  • SiteURI: Fixed a bug in SiteURIFactory::parseRequestURI() where folder names containing multibyte (non-ASCII) characters were not correctly resolved when the application was served from a subfolder.
  • URI: Fixed a bug in URI::getAuthority() where schemes without defined default ports (like rtsp://) would cause issues due to missing array key handling.
