7.5 · HIGHOverview
CVE-2021-41077 is a high-severity vulnerability affecting travis-ci travis_ci. It was published on September 14, 2021 and has a CVSS 3.1 base score of 7.5 (HIGH).
This vulnerability has a CVSS 3.1 base score of 7.5, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.
Technical 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.
Remediation
Check the references section for vendor advisories and patches from travis-ci. Update travis_ci to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
