CVE-2021-41077 Information

Description

The activation process in Travis CI for certain 2021-09-03 through 2021-09-10 builds causes secret data to have unexpected sharing that is not specified by the customer-controlled .travis.yml file. In particular the desired behavior (if .travis.yml has been created locally by a customer and added to git) is for a Travis service to perform builds in a way that prevents public access to customer-specific secret environment data such as signing keys access credentials and API tokens. However during the stated 8-day interval secret data could be revealed to an unauthorized actor who forked a public repository and printed files during a build process.
