Missing Cryptographic Step

jsrsasign is vulnerable to Missing Cryptographic Step. The vulnerability is due to improper handling of invalid DSA signature values without retry logic, which allows an attacker to recover the private key by forcing signature parameters to predictable values...

EUVD-2026-14373

Versions of the package jsrsasign from 7.0.0 and before 11.1.1 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 private key by exploiting the incorrect...

EUVD-2026-14375

Versions of the package jsrsasign before 11.1.1 are vulnerable to Improper Verification of Cryptographic Signature via the DSA domain-parameter validation in KJUR.crypto.DSA.setPublic and the related DSA/X509 verification flow in src/dsa-2.0.js. An attacker can forge DSA signatures or X.509...

Division by zero

Overview org.webjars.npm: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 RS...

Missing Cryptographic Step

Overview org.webjars.npm:jsrsasign is a free pure JavaScript cryptographic library. Affected versions of this package are vulnerable to Missing Cryptographic Step via the KJUR.crypto.DSA.signWithMessageHash process in the DSA signing implementation. An attacker can recover the private key by...

GHSA-G753-JX37-7XWH ECDSA signature vulnerability of Minerva timing attack in jsrsasign

Impact ECDSA side-channel attack named Minerava have been found and it was found that it affects to jsrsasign. Execution time of thousands signature generation have been observed then EC private key which is scalar value may be recovered since point and scalar multiplication time depends on bits ...
