{"id":"CVE-2022-35954","summary":"Delimiter injection vulnerability in @actions/core exportVariable","details":"The GitHub Actions ToolKit provides a set of packages to make creating actions easier. The `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. Users should upgrade to `@actions/core v1.9.1`. If 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`.","aliases":["GHSA-7r3h-m5j6-3q42"],"modified":"2026-05-10T03:52:42.386958Z","published":"2022-08-13T23:40:09Z","database_specific":{"cna_assigner":"GitHub_M","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/35xxx/CVE-2022-35954.json","cwe_ids":["CWE-77"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/35xxx/CVE-2022-35954.json"},{"type":"ADVISORY","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":"FIX","url":"https://github.com/actions/toolkit/commit/4beda9cbc00ba6eefe387a937c21087ccb8ee9df"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/actions/toolkit","events":[{"introduced":"0"},{"fixed":"4beda9cbc00ba6eefe387a937c21087ccb8ee9df"}],"database_specific":{"source":"REFERENCES"}}],"versions":["0.0.0","0.0.1","0.0.2","@actions/core@1.0.0","@actions/core@1.1.0","@actions/exec@1.0.0","@actions/exec@1.0.1","@actions/github@1.0.0","@actions/github@1.1.0","@actions/io@1.0.0","@actions/io@1.0.1","@actions/tool-cache@1.0.0","@actions/tool-cache@1.1.1"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2022-35954.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:L/A:N"}]}
