  "summary" : "GitHub personal access token leaking into temporary EasyBuild (debug) logs",
  "details" : "### Impact\n\nThe GitHub Personal Access Token (PAT) used by EasyBuild for the GitHub integration features (like `--new-pr`, `--from-pr`, etc.) is shown in plain text in EasyBuild debug log files.\n\nScope:\n\n* the log message only appears in the top-level log file, *not* in the individual software installation logs (see https://easybuild.readthedocs.io/en/latest/Logfiles.html);\n    - as a consequence, tokens are *not* included in the partial log files that are uploaded into a gist when using `--upload-test-report` in combination with `--from-pr`, nor in the installation logs that are copied to the software installation directories;\n* the message is only logged when using `--debug`, so it will not appear when using the default EasyBuild configuration (only info messages are logged by default);\n* the log message is triggered via `--from-pr`, but also via various other GitHub integration options like `--new-pr`, `--merge-pr`, `--close-pr`, etc., but usually only appears in the temporary log file that is cleaned up automatically as soon as eb completes successfully;\n* you may have several debug log files that include your GitHub token in `/tmp` (or a different location if you've set the `--tmpdir` EasyBuild configuration option) on the systems where you use EasyBuild, but they are located in a subdirectory that is only accessible to your account (permissions set to 700);\n* the only way that a log file that may include your token could have been made public is *if you shared it yourself*, for example by copying the contents of the log file into a gist manually, or by sending a log file to someone;\n* for log files uploaded to GitHub, your token would be revoked automatically when GitHub notices it;\n\n### Patches\n\nThe issue is fixed with the changes in https://github.com/easybuilders/easybuild-framework/pull/3248.\n\nThis fix is included in EasyBuild v4.1.2 (released on Mon Mar 16th 2020), and in the `master`+  `develop` branches of the `easybuild-framework` repository since Mon Mar 16th 2020 (see https://github.com/easybuilders/easybuild-framework/pull/3248 and https://github.com/easybuilders/easybuild-framework/pull/3249 resp.).\n\n**Make sure you revoke the existing GitHub tokens you're using with EasyBuild** (via https://github.com/settings/tokens), and install new ones using \"`eb --install-github-token --force`\" (see also https://easybuild.readthedocs.io/en/latest/Integration_with_GitHub.html#installing-a-github-token-install-github-token).\n\n### Workarounds\n\n* avoid using the GitHub integration features (see https://easybuild.readthedocs.io/en/latest/Integration_with_GitHub.html) with EasyBuild versions older than version 4.1.2;\n* don't share top-level EasyBuild (debug) log files with others, unless you are sure your GitHub token is not included in them;\n* clean up temporary EasyBuild log files in `/tmp`on the system(s) where you`re using EasyBuild\n\n### References\n\n* https://github.com/easybuilders/easybuild-framework/pull/3248 (PR that fixes the issue)\n* (release announcement to EasyBuild mailing list)\n\n### For more information\n\n* Open an issue in [the `easybuild-framework` repository](https://github.com/easybuilders/easybuild-framework)\n* Email us at [easybuild-admin@lists.ugent.be](mailto:easybuild-admin@lists.ugent.be)",
