CVE-2020-5262

GitHub token disclosure via uncensored request headers

Published Mar 19, 2020 · Updated Aug 4, 2024

Sensitive-data exposure in EasyBuild Framework before 4.1.2 allows local users to obtain a GitHub token from an accessible debug log. The REST client writes the full request-header dictionary, including the Authorization token, to the top-level log before sending GitHub API requests. Exposure requires a GitHub integration option and nondefault debug logging; the temporary log is normally mode 700, limiting disclosure to the account holder or recipients of a manually shared log.
