CodeIgniter before 2.2.0 makes it easier for attackers to decode session cookies by leveraging fallback to a custom XOR-based encryption scheme when the Mcrypt extension for PHP is not available.

CodeIgniter before 3.0 and Kohana 3.2.3 and earlier and 3.3.x through 3.3.2 make it easier for remote attackers to spoof session cookies and consequently conduct PHP object injection attacks by leveraging use of standard string comparison operators to compare cryptographic…

SQL injection vulnerability in the offset method in the Active Record class in CodeIgniter before 2.2.4 allows remote attackers to execute arbitrary SQL commands via vectors involving the offset variable.

system/libraries/Email.php in CodeIgniter before 3.1.3 allows remote attackers to execute arbitrary code by leveraging control over the email->from field to insert sendmail command-line arguments.

### Impact The `ext_in` upload validation rule 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: ```…

British Columbia Institute of Technology CodeIgniter 3.1.3 is vulnerable to HTTP Header Injection in the set_status_header() common function under Apache resulting in HTTP Header Injection flaws.

The xss_clean function in CodeIgniter before 2.1.4 might allow remote attackers to bypass an intended protection mechanism and conduct cross-site scripting (XSS) attacks via an unclosed HTML tag.

EllisLab CodeIgniter 2.1.2 allows remote attackers to bypass the xss_clean() Filter and perform XSS attacks.

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…

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…

CodeIgniter is a PHP full-stack web framework A vulnerability was found in the Language class that allowed DoS attacks. This vulnerability can be exploited by an attacker to consume a large amount of memory on the server. Upgrade to v4.4.7 or later.

CodeIgniter Shield is an authentication and authorization provider for CodeIgniter 4. The `secretKey` value is an important key for HMAC SHA256 authentication and in affected versions was stored in the database in cleartext form. If a malicious person somehow had access to the…

CodeIgniter Shield is an authentication and authorization provider for CodeIgniter 4. In affected versions successful login attempts are recorded with the raw tokens stored in the log table. If a malicious person somehow views the data in the log table they can obtain a raw…

CodeIgniter is a PHP full-stack web framework. Prior to CodeIgniter4 version 4.4.3, if an error or exception occurs, a detailed error report is displayed even if in the production environment. As a result, confidential information may be leaked. Version 4.4.3 contains a patch.…

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…

CodeIgniter Shield provides authentication and authorization for the CodeIgniter 4 PHP framework. An improper implementation was found in the password storage process. All hashed passwords stored in Shield v1.0.0-beta.3 or earlier are easier to crack than expected due to the…

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…

CodeIgniter is a PHP full-stack web framework. This vulnerability may allow attackers to spoof their IP address when the server is behind a reverse proxy. This issue has been patched, please upgrade to version 4.2.11 or later, and configure `Config\App::$proxyIPs`. As a…
