Codeigniter4 vulnerabilities

CVE-2022-21647 [CRITICAL] CWE-502 CVE-2022-21647: CodeIgniter is an open source PHP full-stack web framework. Deserialization of Untrusted Data was fo CodeIgniter is an open source PHP full-stack web framework. Deserialization of Untrusted Data was found in the `old()` function in CodeIgniter4. Remote attackers may inject auto-loadable arbitrary objects with this vulnerability, and possibly execute existing PHP code on the server. We are aware of a working exploit, which can lead to SQL injectio

CVE-2026-63223 [CRITICAL] CWE-434 CVE-2026-63223: CodeIgniter is a PHP full-stack web framework. Prior to 4.7.4, the is_image and mime_in upload valid CodeIgniter is a PHP full-stack web framework. Prior to 4.7.4, the is_image and mime_in upload validation rules do not independently enforce a safe client filename extension, allowing a remote attacker to upload executable content when an application preserves the client filename and stores uploads in a web-accessible script-enabled directory. App

CVE-2025-54418 [CRITICAL] CWE-78 CVE-2025-54418: CodeIgniter is a PHP full-stack web framework. A command injection vulnerability present in versions CodeIgniter is a PHP full-stack web framework.

CVE-2026-48062 [CRITICAL] CWE-434 CVE-2026-48062: CodeIgniter is a PHP full-stack web framework. Prior to 4.7.3, the ext_in upload validation rule in CodeIgniter is a PHP full-stack web framework. Prior to 4.7.3, the ext_in upload validation rule in system/Validation/StrictRules/FileRules.php checked the MIME-derived guessed extension instead of the client-provided filename extension. As a result, an uploaded file named shell.php containing GIF-like content could pass validation such as uploaded

CVE-2026-63221 [CRITICAL] CWE-89 CVE-2026-63221: CodeIgniter is a PHP full-stack web framework. From 4.3.0 through 4.7.3, Query Builder deleteBatch() CodeIgniter is a PHP full-stack web framework. From 4.3.0 through 4.7.3, Query Builder deleteBatch() substitutes bound values from where() conditions into generated SQL while ignoring their escape flags, allowing user-controlled condition values to be interpreted as SQL. This affects only the deleteBatch() code path. Regular delete() operations esc

CVE-2022-24711 [CRITICAL] CWE-20 CVE-2022-24711: CodeIgniter4 is the 4.x branch of CodeIgniter, a PHP full-stack web framework. Prior to version 4.1. CodeIgniter4 is the 4.x branch of CodeIgniter, a PHP full-stack web framework.

CVE-2023-32692 [CRITICAL] CWE-94 CVE-2023-32692: CodeIgniter is a PHP full-stack web framework. This vulnerability allows attackers to execute arbitr CodeIgniter is a PHP full-stack web framework. This vulnerability allows attackers to execute arbitrary code when you use Validation Placeholders. The vulnerability exists in the Validation library, and validation methods in the controller and in-model validation are also vulnerable because they use the Validation library internally. This issue is

CVE-2022-46170 [CRITICAL] CWE-287 CVE-2022-46170: CodeIgniter is a PHP full-stack web framework. When an application uses (1) multiple session cookies CodeIgniter is a PHP full-stack web framework. When an application uses (1) multiple session cookies (e.g., one for user pages and one for admin pages) and (2) a session handler is set to `DatabaseHandler`, `MemcachedHandler`, or `RedisHandler`, then if an attacker gets one session cookie (e.g., one for user pages), they may be able to access page

CVE-2026-63222 [HIGH] CWE-22 CVE-2026-63222: CodeIgniter is a PHP full-stack web framework. Prior to 4.7.4, calling UploadedFile::move() without CodeIgniter is a PHP full-stack web framework. Prior to 4.7.4, calling UploadedFile::move() without a second argument uses the client-provided filename without sanitization, allowing a remote attacker to use path traversal sequences to write uploaded content outside the intended directory when the application exposes an upload path. This issue is fixed

CVE-2022-24712 [HIGH] CWE-352 CVE-2022-24712: CodeIgniter4 is the 4.x branch of CodeIgniter, a PHP full-stack web framework. A vulnerability in ve CodeIgniter4 is the 4.x branch of CodeIgniter, a PHP full-stack web framework. A vulnerability in versions prior to 4.1.9 might allow remote attackers to bypass the CodeIgniter4 Cross-Site Request Forgery (CSRF) protection mechanism. Users should upgrade to version 4.1.9. There are workarounds for this vulnerability, but users will still need to code
