{"id":"GHSA-7r3h-m5j6-3q42","summary":"@actions/core has Delimiter Injection Vulnerability in exportVariable","details":"## Impact\n\nThe `core.exportVariable` function uses a well known delimiter that attackers can use to break out of that specific variable and assign values to other arbitrary variables. Workflows that write untrusted values to the `GITHUB_ENV` file may cause the path or other environment variables to be modified without the intention of the workflow or action author.\n\n## Patches\n\nUsers should upgrade to `@actions/core v1.9.1`.\n\n## Workarounds\n\nIf you are unable to upgrade the `@actions/core` package, you can modify your action to ensure that any user input does not contain the delimiter `_GitHubActionsFileCommandDelimeter_` before calling `core.exportVariable`.\n\n## References\n\n[More information about setting-an-environment-variable in workflows](https://docs.github.com/en/actions/using-workflows/workflow-commands-for-github-actions#setting-an-environment-variable)\n\nIf you have any questions or comments about this advisory:\n* Open an issue in [`actions/toolkit`](https://github.com/actions/toolkit/issues)\n","aliases":["CVE-2022-35954"],"modified":"2023-11-01T04:59:24.982288Z","published":"2022-08-18T19:01:36Z","database_specific":{"cwe_ids":["CWE-74","CWE-77"],"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2022-08-18T19:01:36Z","nvd_published_at":"2022-08-15T11:21:00Z"},"references":[{"type":"WEB","url":"https://github.com/actions/toolkit/security/advisories/GHSA-7r3h-m5j6-3q42"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-35954"},{"type":"WEB","url":"https://github.com/actions/toolkit/commit/4beda9cbc00ba6eefe387a937c21087ccb8ee9df"},{"type":"PACKAGE","url":"https://github.com/actions/toolkit"}],"affected":[{"package":{"name":"@actions/core","ecosystem":"npm","purl":"pkg:npm/%40actions/core"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"1.9.1"}]}],"database_specific":{"last_known_affected_version_range":"\u003c= 1.9.0","source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2022/08/GHSA-7r3h-m5j6-3q42/GHSA-7r3h-m5j6-3q42.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:L/A:N"}]}
