Prior to version 1.4.0, Ed25519 signature verification accepts forged non-canonical signatures where the scalar S is not reduced modulo the group order (`S >= L`). A valid signature and its `S + L` variant both verify in forge, while Node.js `crypto.verify` (OpenSSL-backed) rejects the `S + L` variant, as defined by the specification. This class of signature malleability has been exploited in practice to bypass authentication and authorization logic (see CVE-2026-25793, CVE-2022-35961). Applications relying on signature uniqueness (i.e., dedup by signature bytes, replay tracking, signed-object canonicalization checks) may be bypassed. Version 1.4.0 patches the issue."}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","baseScore":7.5,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"HIGH","availabilityImpact":"NONE"},"exploitabilityScore":3.9,"impactScore":3.6}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-347"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:digitalbazaar:forge:*:*:*:*:*:node.js:*:*","versionEndIncluding":"1.3.3","matchCriteriaId":"46CBC667-ED99-4B5B-89C8-428CF52FD3FB"}]}]}],"references":[{"url":"https://datatracker.ietf.org/doc/html/rfc8032#section-8.4","source":"security-advisories@github.com","tags":["Third Party Advisory"]},{"url":"https://github.com/digitalbazaar/forge/commit/bdecf11571c9f1a487cc0fe72fe78ff6dfa96b85","source":"security-advisories@github.com","tags":["Patch"]},{"url":"https://github.com/digitalbazaar/forge/security/advisories/GHSA-q67f-28xg-22rw","source":"security-advisories@github.com","tags":["Vendor Advisory"]},{"url":"https://github.com/digitalbazaar/forge/security/advisories/GHSA-q67f-28xg-22rw","source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","tags":["Vendor Advisory"]}]}}]}
