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 \u201cgarbage\u201d 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."}], "lastModified": "2026-04-17T21:16:42.030", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:digitalbazaar:forge:*:*:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "824A6B69-D102-48A0-B8F2-24DEC4D749DD", "versionEndExcluding": "1.4.0"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
