How to Fix CVE-2022-45982

To remediate this vulnerability, upgrade all affected Topthink/think 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/think fixed: Latest secure release 
Upgrade topthink/think 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/think

How to Check if You Are Affected

To determine whether your application is affected by CVE-2022-45982, inspect your project dependencies for Topthink/think:

inspect dependencies for topthink/think

Analyze the terminal output to locate any version of Topthink/think 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.

Technical Details
