{"id":"GHSA-rj44-gpjc-29r7","summary":"[thi.ng/egf] Potential arbitrary code execution of `#gpg`-tagged property values","details":"### Impact\n\nPotential for arbitrary code execution in `#gpg`-tagged property values (only if `decrypt: true` option is enabled)\n\n### Patches\n\n[A fix](https://github.com/thi-ng/umbrella/commit/3e14765d6bfd8006742c9e7860bc7d58ae94dfa5) has already been released as v0.4.0\n\n### Workarounds\n\nBy default, EGF parse functions do NOT attempt to decrypt values (since GPG is only available in non-browser env).\n\nHowever, if GPG encrypted values are used/required:\n\n1. Perform a regex search for `#gpg`-tagged values in the EGF source file/string and check for backtick (\\`) chars in the encrypted value string\n2. Replace/remove them or skip parsing if present...\n\n### References\n\nhttps://github.com/thi-ng/umbrella/security/advisories/GHSA-rj44-gpjc-29r7#advisory-comment-65261\n\n### For more information\n\nIf you have any questions or comments about this advisory, please open an issue in the [thi.ng/umbrella repo](https://github.com/thi-ng/umbrella/issues), of which this package is part of.","aliases":["CVE-2021-21412"],"modified":"2026-07-08T06:29:39.326519201Z","published":"2021-04-06T17:22:41Z","database_specific":{"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2021-03-30T17:40:22Z","nvd_published_at":"2021-03-30T18:15:00Z","cwe_ids":["CWE-78"]},"references":[{"type":"WEB","url":"https://github.com/thi-ng/umbrella/security/advisories/GHSA-rj44-gpjc-29r7"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2021-21412"},{"type":"WEB","url":"https://github.com/thi-ng/umbrella/commit/88f61656e5f5cfba960013b8133186389efaf243"},{"type":"WEB","url":"https://github.com/thi-ng/umbrella/blob/develop/packages/egf/CHANGELOG.md#040-2021-03-27"},{"type":"WEB","url":"https://www.npmjs.com/package/@thi.ng/egf"}],"affected":[{"package":{"name":"@thi.ng/egf","ecosystem":"npm","purl":"pkg:npm/%40thi.ng/egf"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"0.4.0"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2021/04/GHSA-rj44-gpjc-29r7/GHSA-rj44-gpjc-29r7.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:L/I:L/A:N"}]}
