CVE-2026-4598
EUVD-2026-1437123.03.2026, 06:16
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 attacker to hang the process permanently by supplying such crafted values (e.g., modInverse(0, m) or modInverse(-1, m)).

Common Weakness Enumeration
- CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')The program contains an iteration or loop with an exit condition that cannot be reached, i.e., an infinite loop.
- CWE-1287 - Improper Validation of Specified Type of InputThe product receives input that is expected to be of a certain type, but it does not validate or incorrectly validates that the input is actually of the expected type.
