How to Fix GHSA-q9j3-4ghj-6h57

To remediate this vulnerability, upgrade all affected Codeigniter/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.

codeigniter/framework fixed: 3.0.3
Upgrade codeigniter/framework to 3.0.3
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 codeigniter/framework

How to Check if You Are Affected

To determine whether your application is affected by GHSA-q9j3-4ghj-6h57, inspect your project dependencies for Codeigniter/framework:

inspect dependencies for codeigniter/framework

Analyze the terminal output to locate any version of Codeigniter/framework in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.0.3), 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-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'), where the product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. In Codeigniter/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

The xss_clean() method in the Security Library of CodeIgniter/Framework, specifically in versions before 3.0.3, exhibited a vulnerability that allowed certain Cross-Site Scripting (XSS) vectors to bypass its intended protection mechanisms. The xss_clean() method is designed to sanitize input data by removing potentially malicious content, thus preventing XSS attacks. However, in versions prior to 3.0.3, it was discovered that the method did not adequately mitigate specific XSS vectors, leaving a potential security gap.
