Prior to version 1.4.0, a Denial of Service (DoS) vulnerability exists in the node-forge library due to an infinite loop in the BigInteger.modInverse() function (inherited from the bundled jsbn library). When modInverse() is called with a zero value as input, the internal Extended Euclidean Algorithm enters an unreachable exit condition, causing the process to hang indefinitely and consume 100% CPU. Version 1.4.0 patches the issue.","state":0,"publishedAt":"2026-03-27T21:17:25.817+00:00","modifiedAt":"2026-10-26T22:10:00.163+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5,"severity":"HIGH"},{"system":"CVSS 3.1 · 0b0ca135-0b70-47e7-9f44-1890c2a1c46c · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5,"severity":"HIGH"}],"references":["https://github.com/digitalbazaar/forge/commit/9bb8d67b99d17e4ebb5fd7596cd699e11f25d023","https://github.com/digitalbazaar/forge/security/advisories/GHSA-5m6q-g25r-mvwx","https://access.redhat.com/errata/RHSA-2026:13826","https://access.redhat.com/errata/RHSA-2026:24761","https://access.redhat.com/errata/RHSA-2026:24762","https://access.redhat.com/errata/RHSA-2026:34342","https://access.redhat.com/errata/RHSA-2026:9742","https://access.redhat.com/security/cve/CVE-2026-33891","https://bugzilla.redhat.com/show_bug.cgi?id=2452450","https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-33891.json"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-33891","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Modified","weaknesses":["CWE-835","CWE-606"],"productCriteria":["cpe:2.3:a:digitalbazaar:forge:*:*:*:*:*:node.js:*:*"],"sourceDates":{"published":"2026-03-27T21:17:25.817","lastModified":"2026-10-26T22:10:00.163"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
