Prior to version 1.4.0, RSASSA PKCS#1 v1.5 signature verification accepts forged signatures for low public exponent keys (e=3). Attackers can forge signatures by stuffing “garbage” bytes within the ASN structure in order to construct a signature that passes verification, enabling Bleichenbacher style forgery. This issue is similar to CVE-2022-24771, but adds bytes in an addition field within the ASN structure, rather than outside of it.  Additionally, forge does not validate that signatures include a minimum of 8 bytes of padding as defined by the specification, providing attackers additional space to construct Bleichenbacher forgeries. Version 1.4.0 patches the issue.","state":0,"publishedAt":"2026-03-27T21:17:25.983+00:00","modifiedAt":"2026-09-10T13:18:25.977+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:H/A:N","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:H/A:N","score":7.5,"severity":"HIGH"}],"references":["https://datatracker.ietf.org/doc/html/rfc2313#section-8","https://github.com/digitalbazaar/forge/security/advisories/GHSA-ppp5-5v6c-4jwp","https://mailarchive.ietf.org/arch/msg/openpgp/5rnE9ZRN1AokBVj3VqblGlP63QE","https://www.rfc-editor.org/rfc/rfc8017.html","https://access.redhat.com/errata/RHSA-2026:13826","https://access.redhat.com/errata/RHSA-2026:19375","https://access.redhat.com/errata/RHSA-2026:21017","https://access.redhat.com/errata/RHSA-2026:22465","https://access.redhat.com/errata/RHSA-2026:22629","https://access.redhat.com/errata/RHSA-2026:22840","https://access.redhat.com/errata/RHSA-2026:23361","https://access.redhat.com/errata/RHSA-2026:24761","https://access.redhat.com/errata/RHSA-2026:24853","https://access.redhat.com/errata/RHSA-2026:34342","https://access.redhat.com/errata/RHSA-2026:9742","https://access.redhat.com/security/cve/CVE-2026-33894","https://bugzilla.redhat.com/show_bug.cgi?id=2452464","https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-33894.json"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-33894","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Modified","weaknesses":["CWE-20","CWE-347"],"productCriteria":["cpe:2.3:a:digitalbazaar:forge:*:*:*:*:*:node.js:*:*"],"sourceDates":{"published":"2026-03-27T21:17:25.983","lastModified":"2026-09-10T13:18:25.977"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
