A Travis CI continuous integration service designed for testing and building projects developed on GitHub and Bitbucket has revealed a security issue (CVE-2021-41077) that allows access to the contents of sensitive environment variables in public repositories using Travis CI. This vulnerability also exposes the keys for generating digital signatures, access keys, and tokens used to interact with the API. <\/p>\n
The issue was present in Travis CI from September 3 to 10. Notably, the information regarding the vulnerability was passed to the developers on September 7, but only a generic response was received recommending the rotation of keys. After receiving insufficient feedback, the researchers contacted GitHub and proposed blacklisting Travis. The problem was resolved only on September 10 after a large number of complaints from various projects. Following the incident, a rather strange report about the issue was published on the Travis CI website, which instead of informing about the vulnerability fix contained only the aforementioned out-of-context recommendation to cyclically change access keys. <\/p>\n
