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.","published":"2021-03-30T18:15:15.840Z","modified":"2026-07-09T14:06:34.571254Z","cvss":{"score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"npm","name":"@thi.ng/egf","fixedVersion":"0.4.0"}],"fix":{"url":"https://github.com/thi-ng/umbrella/commit/88f61656e5f5cfba960013b8133186389efaf243","label":"thi-ng/umbrella@88f6165"},"references":[{"type":"WEB","url":"https://www.npmjs.com/package/%40thi.ng/egf"},{"type":"ADVISORY","url":"https://github.com/thi-ng/umbrella/blob/develop/packages/egf/CHANGELOG.md#040-2021-03-27"},{"type":"FIX","url":"https://github.com/thi-ng/umbrella/commit/88f61656e5f5cfba960013b8133186389efaf243"},{"type":"FIX","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://www.npmjs.com/package/@thi.ng/egf"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-09T14:06:34.571254Z"}}
