How to Fix CVE-2024-29904

To remediate this vulnerability, upgrade all affected Codeigniter4/framework dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

codeigniter4/framework fixed: 4.4.7 
Upgrade codeigniter4/framework to 4.4.7
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for codeigniter4/framework

How to Check if You Are Affected

To determine whether your application is affected by CVE-2024-29904, inspect your project dependencies for Codeigniter4/framework:

inspect dependencies for codeigniter4/framework

Analyze the terminal output to locate any version of Codeigniter4/framework in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.4.7), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop'), where the product contains an iteration or loop with an exit condition that cannot be reached, i.e., an infinite loop. In Codeigniter4/framework, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact 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. ### Patches Upgrade to v4.4.7 or later. See [upgrading guide](https://codeigniter4.github.io/userguide/installation/upgrade_447.html). ### Workarounds - Disabling Auto Routing prevents a known attack vector in the framework. - Do not pass invalid values to the `lang()` function or `Language` class. ### References - https://codeigniter4.github.io/userguide/outgoing/localization.html#language-localization - https://codeigniter4.github.io/userguide/general/common_functions.html#lang
