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 service’s web application firewall interprets them as malicious and blocks further communication with the application. This vulnerability is fixed in 4.5.8.

A vulnerability classified as problematic has been found in CodeIgniter Ecommerce-CodeIgniter-Bootstrap up to 1998845073cf433bc6c250b0354461fbd84d0e03. This affects an unknown part. The manipulation of the argument search_title/catName/sub/name/categorie leads to cross site scripting. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used. The identifier of the patch is 1b3da45308bb6c3f55247d0e99620b600bd85277. It is recommended to apply a patch to fix this issue. The identifier VDB-270369 was assigned to this vulnerability.

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. 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 token which can then be used to send a request with that user's authority. This issue has been addressed in version 1.0.0-beta.8. Users are advised to upgrade. Users unable to upgrade should disable logging for successful login attempts by the configuration files.

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 data in the database, they could use the key and secretKey for HMAC SHA256 authentication to send requests impersonating that corresponding user. This issue has been addressed in version 1.0.0-beta.8. Users are advised to upgrade. There are no known workarounds for this vulnerability.

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. As a workaround, replace `ini_set('display_errors', '0')` with `ini_set('display_errors', 'Off')` in `app/Config/Boot/production.php`.

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 patched in version 4.3.5.

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 vulnerability. Therefore, they should be removed as soon as possible. If an attacker gets (1) the user's hashed password by Shield, and (2) the hashed password (SHA-384 hash without salt) from somewhere, the attacker may easily crack the user's password. Upgrade to Shield v1.0.0-beta.4 or later to fix this issue. After upgrading, all users’ hashed passwords should be updated (saved to the database). There are no known workarounds.

Cross Site Scripting (XSS) vulnerability in Ecommerce-CodeIgniter-Bootstrap thru commit d5904379ca55014c5df34c67deda982c73dc7fe5 (on Dec 27, 2022), allows attackers to execute arbitrary code via the languages and trans_load parameters in file add_product.php.

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.
