{"id":"CVE-2026-118782","summary":"Forge: PKCS#12 MAC forgery and constant-key PBE via zero iteration count","details":"Forge (also called node-forge) is a native implementation of Transport Layer Security in JavaScript. Prior to 1.4.1, node-forge accepted a PKCS#12 MAC or PKCS#12 password-based encryption iteration count of zero or less. pki.pbe.generatePkcs12Key() then returned a constant key independent of the password and salt, allowing crafted PKCS#12 input processed by forge.pkcs12.pkcs12FromAsn1() to bypass password-based integrity checks. Predictable encryption keys and IVs also affected PKCS#12 PBE using pbeWithSHAAnd3-KeyTripleDES-CBC or pbewithSHAAnd40BitRC2-CBC, including shrouded key bags, encrypted SafeContents, and PKCS#8 ENCRYPTED PRIVATE KEY input processed independently by forge.pki.decryptPrivateKeyInfo(). PBES2/PBKDF2-encrypted content is unaffected. This issue is fixed in version 1.4.1.","aliases":["GHSA-jc66-7q78-782g"],"modified":"2026-11-01T02:47:22.250201167Z","published":"2026-10-29T18:51:02.388Z","database_specific":{"cwe_ids":["CWE-1284","CWE-354"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/118xxx/CVE-2026-118782.json","cna_assigner":"GitHub_M"},"references":[{"type":"WEB","url":"https://github.com/digitalbazaar/forge/releases/tag/v1.4.1"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/118xxx/CVE-2026-118782.json"},{"type":"ADVISORY","url":"https://github.com/digitalbazaar/forge/security/advisories/GHSA-jc66-7q78-782g"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-118782"},{"type":"FIX","url":"https://github.com/digitalbazaar/forge/commit/d9584aa56824972858366d5187b3d29e46bf3656"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/digitalbazaar/forge","events":[{"introduced":"0"},{"fixed":"8a917370ec51731e817c2d547b7329a58f8210af"},{"fixed":"d9584aa56824972858366d5187b3d29e46bf3656"}],"database_specific":{"extracted_events":[{"source":"AFFECTED_FIELD","strategy":"StringRangeExpression","range":[{"introduced":"0"},{"fixed":"1.4.1"}]},{"range":[{"fixed":"d9584aa56824972858366d5187b3d29e46bf3656"}],"source":"REFERENCES_COMMIT"},{"original_tag":"v1.4.1","range":[{"fixed":"8a917370ec51731e817c2d547b7329a58f8210af"}],"source":"REFERENCES_TAG"}]}}],"versions":["v1.4.0","v1.3.3","v1.3.2","v1.3.1","v1.3.0","v1.2.1","v1.2.0","v1.1.0","v1.0.0","0.10.0","0.9.2","0.9.1","0.9.0","0.8.5","0.8.4","0.8.3","0.8.2","0.8.1","0.8.0","0.7.6","0.7.5","0.7.4","0.7.3","0.7.2","0.7.1","0.7.0","0.6.46","0.6.45","0.6.44","0.6.43","0.6.42","0.6.41","0.6.40","0.6.39","0.6.38","0.6.37","0.6.35","0.6.34","0.6.33","0.6.32","0.6.31","0.6.30","0.6.29","0.6.28","0.6.27","0.6.26","0.6.25","0.6.24","0.6.23","0.6.22","0.6.21","0.6.20","0.6.18","0.6.17","0.6.16","0.6.13","0.6.12","0.6.11","0.6.10","0.6.9","0.6.8","0.6.7","0.6.6","0.6.5","0.6.4","0.6.3","0.6.2","0.6.1","0.6.0","0.5.5","0.5.4","0.5.3","0.5.2","0.5.1","0.4.3","0.4.2","0.4.1","0.4.0","0.3.0","0.2.37","0.2.36","0.2.35","0.2.34","0.2.33","0.2.32","0.2.31","0.2.30","0.2.29","0.2.28","0.2.27","0.2.26","0.2.25","0.2.24","0.2.23","0.2.22","0.2.21","0.2.20","0.2.19","0.2.18","0.2.17","0.2.15","0.2.14","0.2.13","0.2.12","0.2.11","0.2.10","0.2.9","0.2.8","0.2.7","0.2.6","0.2.5","0.2.4","0.2.3","0.2.2","0.2.1","0.2.0","0.1.15","0.1.14","0.1.13","0.1.12","0.1.11","0.1.10","0.1.9","0.1.8","0.1.7","0.1.6","0.1.5","0.1.4","0.1.3","0.1.2"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-118782.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N"}]}
