| CVE | Severidad | EPSS | Explotación activa | Publicada | Descripción |
|---|---|---|---|---|---|
| CVE-2026-4603 | Baja (2) | 0.11% | — | 23 mar 2026 | Versions of the package jsrsasign before 11.1.1 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… |
| CVE-2026-4602 | Alta (7.7) | 0.88% | — | 23 mar 2026 | Versions of the package jsrsasign before 11.1.1 are vulnerable to Incorrect Conversion between Numeric Types due to handling negative exponents in ext/jsbn2.js. An attacker can force the computation of incorrect modular… |
| CVE-2026-4601 | Alta (8.8) | 0.47% | — | 23 mar 2026 | Versions of the package jsrsasign before 11.1.1 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… |
| CVE-2026-4600 | Alta (8.1) | 0.32% | — | 23 mar 2026 | 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… |
| CVE-2026-4599 | Crítica (9.3) | 0.78% | — | 23 mar 2026 | 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… |
| CVE-2026-4598 | Alta (7.7) | 0.96% | — | 23 mar 2026 | Versions of the package jsrsasign before 11.1.1 are vulnerable to Infinite loop via the bnModInverse function in ext/jsbn2.js when the BigInteger.modInverse implementation receives zero or negative inputs, allowing an… |
| CVE-2025-45764 | Baja (3.2) | 0.06% | — | 6 ago 2025 | 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… |
| CVE-2024-21484 | Media (5.9) | 0.96% | — | 22 ene 2024 | Versions of the package jsrsasign before 11.0.0 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.… |
| CVE-2022-25898 | Crítica (9.8) | 1.2% | — | 1 jul 2022 | The package jsrsasign before 10.5.25 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… |
| CVE-2021-30246 | Crítica (9.1) | 0.96% | — | 7 abr 2021 | In the jsrsasign package through 10.1.13 for Node.js, some invalid RSA PKCS#1 v1.5 signatures are mistakenly recognized to be valid. NOTE: there is no known practical attack. |
| CVE-2020-14968 | Crítica (9.8) | 2.9% | — | 22 jun 2020 | An issue was discovered in the jsrsasign package before 8.0.17 for Node.js. Its RSASSA-PSS (RSA-PSS) implementation does not detect signature manipulation/modification by prepending '\0' bytes to a signature (it accepts… |
| CVE-2020-14967 | Crítica (9.8) | 2.3% | — | 22 jun 2020 | An issue was discovered in the jsrsasign package before 8.0.18 for Node.js. Its RSA PKCS1 v1.5 decryption implementation does not detect ciphertext modification by prepending '\0' bytes to ciphertexts (it decrypts… |
| CVE-2020-14966 | Alta (7.5) | 1.1% | — | 22 jun 2020 | An issue was discovered in the jsrsasign package through 8.0.18 for Node.js. It allows a malleability in ECDSA signatures by not checking overflows in the length of a sequence and '0' characters appended or prepended to… |
