How to Fix CVE-2017-1000247

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: 3.1.4 
Upgrade codeigniter4/framework to 3.1.4
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-2017-1000247, 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 3.1.4), your application is affected.

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