What fixes it

A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.

Description

Insecure file permissions in the CodeCatalyst connection handler in AWS Toolkit for VS Code before 4.10.0 allowed local users to obtain CodeCatalyst bearer tokens via reading world-readable token cache files.

To mitigate this issue, users should upgrade to version 4.10.0 or later.
