The `tj-actions/branch-names` GitHub Actions improperly references the `github.event.pull_request.head.ref` and `github.head_ref` context variables within a GitHub Actions `run` step. The head ref variable is the branch name and can be used to execute arbitrary code using a specially crafted branch name. As a result an attacker can use this vulnerability to steal secrets from or abuse `GITHUB_TOKEN` permissions. This vulnerability has been addressed in version 7.0.7. Users are advised to upgrade. There are no known workarounds for this vulnerability."}],"source":{"advisory":"GHSA-8v8w-v8xg-79rf","discovery":"UNKNOWN"}},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-02T21:53:44.957Z"},"title":"CVE Program Container","references":[{"name":"https://github.com/tj-actions/branch-names/security/advisories/GHSA-8v8w-v8xg-79rf","tags":["x_refsource_CONFIRM","x_transferred"],"url":"https://github.com/tj-actions/branch-names/security/advisories/GHSA-8v8w-v8xg-79rf"},{"name":"https://github.com/tj-actions/branch-names/commit/4923d1ca41f928c24f1c1b3af9daaadfb71e6337","tags":["x_refsource_MISC","x_transferred"],"url":"https://github.com/tj-actions/branch-names/commit/4923d1ca41f928c24f1c1b3af9daaadfb71e6337"},{"name":"https://github.com/tj-actions/branch-names/commit/6c999acf206f5561e19f46301bb310e9e70d8815","tags":["x_refsource_MISC","x_transferred"],"url":"https://github.com/tj-actions/branch-names/commit/6c999acf206f5561e19f46301bb310e9e70d8815"},{"name":"https://github.com/tj-actions/branch-names/commit/726fe9ba5e9da4fcc716223b7994ffd0358af060","tags":["x_refsource_MISC","x_transferred"],"url":"https://github.com/tj-actions/branch-names/commit/726fe9ba5e9da4fcc716223b7994ffd0358af060"},{"name":"https://securitylab.github.com/research/github-actions-untrusted-input","tags":["x_refsource_MISC","x_transferred"],"url":"https://securitylab.github.com/research/github-actions-untrusted-input"}]}]}}
