Release Date: Unreleased

4.6.2 release of CodeIgniter4

BREAKING

Message Changes

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().

  • 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.

  • 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.
