Last modified

CVE-2021-41077 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. 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. EPSS estimates a 1.44% chance of exploitation in the next 30 days.

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.
