CodeIgniter <4.6.2 RCE via ImageMagick Command Injection
CVE-2025-54418 - July 28, 2025

CodeIgniter is a PHP full-stack web framework. A command injection vulnerability present in versions prior to 4.6.2 affects applications that use the ImageMagick handler for image processing (`imagick` as the image library) and either allow file uploads with user-controlled filenames and process uploaded images using the `resize()` method or use the `text()` method with user-controlled text content or options. An attacker can upload a file with a malicious filename containing shell metacharacters that get executed when the image is processed or provide malicious text content or options that get executed when adding text to images Users should upgrade to v4.6.2 or later to receive a patch. As a workaround, switch to the GD image handler (`gd`, the default handler), which is not affected by either vulnerability. For file upload scenarios, instead of using user-provided filenames, generate random names to eliminate the attack vector with `getRandomName()` when using the `move()` method, or use the `store()` method, which automatically generates safe filenames. For text operations, if one must use ImageMagick with user-controlled text, sanitize the input to only allow safe characters and validate/restrict text options.

Shell injection

Stored XSS in CodeIgniter4 v4.6.0 debugbar_time Parameter
CVE-2025-45406 - July 25, 2025

A stored cross-site scripting (XSS) vulnerability in CodeIgniter4 v4.6.0 allows attackers to execute arbitrary web scripts or HTML via a crafted payload injected into the debugbar_time parameter. NOTE: this is disputed by the Supplier because attackers cannot influence the value of debugbar_time, and because debugbar-related data is automatically escaped by the CodeIgniter Parser class.

CodeIgniter Prior 4.5.8 Header Validation Flaw (CVE-2025-24013)
CVE-2025-24013 - January 20, 2025

CodeIgniter is a PHP full-stack web framework. Prior to 4.5.8, CodeIgniter lacked proper header validation for its name and value. The potential attacker can construct deliberately malformed headers with Header class. This could disrupt application functionality, potentially causing errors or generating invalid HTTP requests. In some cases, these malformed requests might lead to a DoS scenario if a remote services web application firewall interprets them as malicious and blocks further communication with the application. This vulnerability is fixed in 4.5.8.

CodeIgniter is a PHP full-stack web framework
CVE-2022-46170 9.8 - Critical - December 22, 2022

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 pages that require another session cookie (e.g., for admin pages). This issue has been patched, please upgrade to version 4.2.11 or later. As a workaround, use only one session cookie.

SQL Injection

CodeIgniter is a PHP full-stack web framework
CVE-2022-39284 4.3 - Medium - October 06, 2022

CodeIgniter is a PHP full-stack web framework. In versions prior to 4.2.7 setting `$secure` or `$httponly` value to `true` in `Config\Cookie` is not reflected in `set_cookie()` or `Response::setCookie()`. As a result cookie values are erroneously exposed to scripts. It should be noted that this vulnerability does not affect session cookies. Users are advised to upgrade to v4.2.7 or later. Users unable to upgrade are advised to manually construct their cookies either by setting the options in code or by constructing Cookie objects. Examples of each workaround are available in the linked GHSA.

Incorrect Permission Assignment for Critical Resource

Shield is an authentication and authorization framework for CodeIgniter 4
CVE-2022-35943 8.8 - High - August 12, 2022

Shield is an authentication and authorization framework for CodeIgniter 4. This vulnerability may allow [SameSite Attackers](https://canitakeyoursubdomain.name/) to bypass the [CodeIgniter4 CSRF protection](https://codeigniter4.github.io/userguide/libraries/security.html) mechanism with CodeIgniter Shield. For this attack to succeed, the attacker must have direct (or indirect, e.g., XSS) control over a subdomain site (e.g., `https://a.example.com/`) of the target site (e.g., `http://example.com/`). Upgrade to **CodeIgniter v4.2.3 or later** and **Shield v1.0.0-beta.2 or later**. As a workaround: set `Config\Security::$csrfProtection` to `'session,'`remove old session data right after login (immediately after ID and password match) and regenerate CSRF token right after login (immediately after ID and password match)

Improper Input Validation

CodeIgniter4 is the 4.x branch of CodeIgniter, a PHP full-stack web framework
CVE-2022-24712 8.8 - High - February 28, 2022

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 as these after upgrading to v4.1.9. Otherwise, the CSRF protection may be bypassed. If auto-routing is enabled, check the request method in the controller method before processing. If auto-routing is disabled, either avoid using `$routes->add()` and instead use HTTP verbs in routes; or check the request method in the controller method before processing.

Marshaling, Unmarshaling

CodeIgniter through 4.0.0 allows remote attackers to gain privileges via a modified Email ID to the "Select Role of the User" page
CVE-2020-10793 8.8 - High - March 23, 2020

CodeIgniter through 4.0.0 allows remote attackers to gain privileges via a modified Email ID to the "Select Role of the User" page. NOTE: A contributor to the CodeIgniter framework argues that the issue should not be attributed to CodeIgniter. Furthermore, the blog post reference shows an unknown website built with the CodeIgniter framework but that CodeIgniter is not responsible for introducing this issue because the framework has never provided a login screen, nor any kind of login or user management facilities beyond a Session library. Also, another reporter indicates the issue is with a custom module/plugin to CodeIgniter, not CodeIgniter itself.
