Prior to 1.4.1, node-forge did not validate the AES-GCM tagLength option passed to start() during decryption through forge.cipher.createDecipher(). When an application derived tagLength from received data or used an unset or zero-like configuration value, a value that converted to zero together with an empty or missing authentication tag caused the calculated and supplied tags to compare as empty, so decipher.finish() accepted unauthenticated ciphertext. Applications that omit tagLength to use the 128-bit default or pass a fixed valid tag length are unaffected. This issue is fixed in version 1.4.1.","state":0,"publishedAt":"2026-10-29T20:17:29.5+00:00","modifiedAt":"2026-10-30T17:18:03.88+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:N","score":5.9,"severity":"MEDIUM"}],"references":["https://github.com/digitalbazaar/forge/commit/236845d96c71207259f91638d0138bba8e2fd624","https://github.com/digitalbazaar/forge/releases/tag/v1.4.1","https://github.com/digitalbazaar/forge/security/advisories/GHSA-5cwg-6vw7-rj6p"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-119186","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Undergoing Analysis","weaknesses":["CWE-354","CWE-1284"],"productCriteria":[],"sourceDates":{"published":"2026-10-29T20:17:29.500","lastModified":"2026-10-30T17:18:03.880"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
