Description
Improper link resolution before file access in the asset bundling output handling in AWS aws-cdk-lib before 2.267.0 might allow a context-dependent actor to cause files from the build host to be published as the deployed asset. To remediate this issue, users should upgrade to version 2.267.0 or later.
