How to Fix CVE-2022-33107

To remediate this vulnerability, upgrade all affected Topthink/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.

topthink/framework fixed: Latest secure release 
Upgrade topthink/framework to Latest secure release
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 topthink/framework

How to Check if You Are Affected

To determine whether your application is affected by CVE-2022-33107, inspect your project dependencies for Topthink/framework:

inspect dependencies for topthink/framework

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

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