bn.js affected by an infinite loop

CVE-2026-2739 / GHSA-378v-28hj-76wf

More information

Details

This affects versions of the package bn.js before 4.12.3 and 5.2.3. Calling maskn(0) on any BN instance corrupts the internal state, causing toString(), divmod(), and other methods to enter an infinite loop, hanging the process indefinitely.
