CVE-2021-22539

An attacker can place a crafted JSON config file into the project folder pointing to a custom executable. VScode-bazel allows the workspace path to lint *.bzl files to be set via this config file. As such the attacker is able to execute any executable on the system through vscode-bazel. We recommend upgrading to version 0.4.1 or above.
