v4.7.4 (2026-07-07)

Full Changelog

Security

  • IncomingRequest: HTTPS detection via client-supplied headers was fixed. IncomingRequest::isSecure() now trusts the X-Forwarded-Proto and Front-End-Https headers only when the request comes from a trusted proxy configured in Config\App::$proxyIPs. See the Security advisory GHSA-7wmf-pw8j-mc78 <https://github.com/codeigniter4/CodeIgniter4/security/advisories/GHSA-7wmf-pw8j-mc78>_ for more information.

  • Query Builder: Fixed a SQL injection vulnerability in deleteBatch(). When deleteBatch() was used together with where() conditions, the bound values from the WHERE clause were substituted into the generated SQL with their escape flag ignored, so they were never escaped or quoted. The WHERE binds are now escaped in the same way as a regular delete().

    See the Security advisory GHSA-c9w5-rwh3-7pm9 <https://github.com/codeigniter4/CodeIgniter4/security/advisories/GHSA-c9w5-rwh3-7pm9>_ for more information.

  • UploadedFile: UploadedFile::move() now sanitizes the client-provided filename when called without a second argument. Previously, the unsanitized client filename was used as the default, allowing path traversal sequences (e.g. ../../public/shell.php) to write the uploaded file outside the intended directory. A name explicitly passed as the second argument is not sanitized and remains the caller's responsibility. See the Security advisory GHSA-hhmc-q9hp-r662 <https://github.com/codeigniter4/CodeIgniter4/security/advisories/GHSA-hhmc-q9hp-r662>_ for more information.

  • Validation: The is_image and mime_in file upload validation rules now also verify non-empty client filename extensions. Previously, these rules classified an upload solely by its content-derived MIME type, so a file with a dangerous client extension (for example, a .php file prepended with image magic bytes) could pass validation while keeping its original extension on disk. See the Security advisory GHSA-mmj4-63m4-r6h5 <https://github.com/codeigniter4/CodeIgniter4/security/advisories/GHSA-mmj4-63m4-r6h5>_ for more information.

    The is_image rule now rejects uploads when a non-empty client filename extension is not an image extension. The mime_in rule now rejects uploads when a non-empty client filename extension does not match the detected file content, matching the same extension/content agreement used by ext_in. Files uploaded without any extension (such as JavaScript Blob uploads) are still accepted, since the rules validate the file content.

v4.7.3 (2026-05-22)

Full Changelog

Security

  • Validation: Uploaded file extension validation bypass in ext_in rule The ext_in file upload validation rule now validates the client filename extension and verifies that it matches the detected MIME type. Previously, ext_in only checked the MIME-derived guessed extension, so a file with a mismatched client extension could pass validation.

    See the GHSA-2gr4-ppc7-7mhx security advisory for more information. Credits to @z3moo and @teebow1e for reporting the issue.
