CVE-2026-4599

JSrsasign versions 7.0.0–11.0.x are vulnerable due to Incomplete Comparison with Missing Factors in src/crypto-1.1.js: getRandomBigIntegerZeroToMax and getRandomBigIntegerMinToMax perform incorrect compareTo checks that accept out-of-range candidates, biasing DSA nonces and enabling private key r...

CVE-2026-4600

CVE-2026-4600 affects the JavaScript library jsrsasign prior to 11.1.1. The vulnerability stems from improper verification of cryptographic signatures due to DSA domain-parameter validation in KJUR.crypto.DSA.setPublic (and related DSA/X509 verification in src/dsa-2.0.js). An attacker can forge D...

jsrsasign 安全漏洞

jsrsasign is a signature verification library developed by Kenji Urushima. Versions of jsrsasign prior to 11.1.1 contained security vulnerabilities. These vulnerabilities stemmed from improper validation of DSA domain parameters in the src/dsa-2.0.js file, which could lead to the creation of forg...

jsrsasign 安全漏洞

jsrsasign is a signature verification library developed by Kenji Urushima. Versions of jsrsasign prior to 11.1.1 contained security vulnerabilities. These vulnerabilities stemmed from the lack of encryption steps in the DSA signature implementation, which could lead to the exposure of private key...

Division by zero

Overview jsrsasign is a free pure JavaScript cryptographic library. Affected versions of this package are vulnerable to Division by zero due to the RSASetPublic/KEYUTIL parsing path in ext/rsa.js and the BigInteger.modPowInt reduction logic in ext/jsbn.js. An attacker can force RSA public-key...

Incomplete Comparison with Missing Factors

Overview jsrsasign is a free pure JavaScript cryptographic library. Affected versions of this package are vulnerable to Incomplete Comparison with Missing Factors via the getRandomBigIntegerZeroToMax and getRandomBigIntegerMinToMax functions in src/crypto-1.1.js; an attacker can recover the priva...

CVE-2025-45764

jsrsasign v11.1.0 was discovered to contain weak encryption. NOTE: this issue has been disputed by a third party who believes that CVE IDs can be assigned for key lengths in specific applications that use a library, and should not be assigned to the default key lengths in a library. This dispute ...

Observable Discrepancy

Overview jsrsasign is a free pure JavaScript cryptographic library. Affected versions of this package are vulnerable to Observable Discrepancy via the RSA PKCS1.5 or RSAOAEP decryption process. An attacker can decrypt ciphertexts by exploiting the Marvin security flaw. Exploiting this vulnerabili...

Improper Verification of Cryptographic Signature

Overview jsrsasign is a free pure JavaScript cryptographic library. Affected versions of this package are vulnerable to Improper Verification of Cryptographic Signature when JWS or JWT signature with non Base64URL encoding special characters or number escaped characters may be validated as valid ...

GHSA-XXXQ-CHMP-67G4 RSA PKCS#1 decryption vulnerability with prepending zeros in jsrsasign

Impact Jsrsasign supports RSA PKCS1 v1.5 i.e. RSAES-PKCS1-v15 and RSA-OAEP encryption and decryption. Its encrypted message is represented as BigInteger. When there is a valid encrypted message, a crafted message with prepending zeros can be decrypted by this vulnerability. - If you don't use RSA...
