{"id":"GHSA-qwp8-x4ff-5h87","summary":"ZX Allows Environment Variable Injection for dotenv API","details":"### Impact\nThis vulnerability is an **Environment Variable Injection** issue in `dotenv.stringify`, affecting `google/zx`  version **8.3.1**.\n\nAn attacker with control over environment variable values can inject unintended environment variables into `process.env`. This can lead to **arbitrary command execution** or **unexpected behavior** in applications that rely on environment variables for security-sensitive operations. Applications that process untrusted input and pass it through `dotenv.stringify` are particularly vulnerable.\n\n### Patches\nThis issue has been **patched** in version **8.3.2**. Users should **immediately upgrade** to this version to mitigate the vulnerability.\n\n### Workarounds\nIf upgrading is not feasible, users can mitigate the vulnerability by **sanitizing user-controlled environment variable values** before passing them to `dotenv.stringify`. Specifically, avoid using `\"`, `'`, and backticks in values, or enforce strict validation of environment variables before usage.\n\n### References\n- [Issue Report](https://github.com/google/zx/issues/)\n- [Security Policy](https://github.com/google/zx/security/policy)\n- [Google Vulnerability Disclosure](https://g.co/vulnz)\n- [Patch](https://github.com/google/zx/pull/1094)","aliases":["CVE-2025-24959"],"modified":"2025-02-04T17:29:11Z","published":"2025-02-03T22:34:08Z","database_specific":{"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2025-02-03T22:34:08Z","nvd_published_at":"2025-02-03T21:15:15Z","cwe_ids":["CWE-74"]},"references":[{"type":"WEB","url":"https://github.com/google/zx/security/advisories/GHSA-qwp8-x4ff-5h87"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-24959"},{"type":"WEB","url":"https://github.com/google/zx/pull/1094"},{"type":"WEB","url":"https://github.com/google/zx/commit/5ba714d14ecf0555a74d4db96622840ac19839c5"},{"type":"PACKAGE","url":"https://github.com/google/zx"},{"type":"WEB","url":"https://github.com/webpod/envapi/blob/v0.2.1/src/main/ts/envapi.ts#L74-L77"}],"affected":[{"package":{"name":"zx","ecosystem":"npm","purl":"pkg:npm/zx"},"ranges":[{"type":"SEMVER","events":[{"introduced":"8.3.1"},{"fixed":"8.3.2"}]}],"versions":["8.3.1"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2025/02/GHSA-qwp8-x4ff-5h87/GHSA-qwp8-x4ff-5h87.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:A/AC:L/PR:L/UI:R/S:U/C:N/I:N/A:H"}]}
