Unintended Secret Data Sharing Vulnerability in Travis CI Activation Process

CVE-2021-41077 · HIGH Severity

CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N

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.
