How to fix?

Upgrade simplito/elliptic-php to version 1.0.6 or higher.

Overview

simplito/elliptic-php is a Fast, general Elliptic Curve Cryptography library.

Affected versions of this package are vulnerable to Timing Attack. Practical recovery of the long-term private key generated by the library is possible under certain conditions. Leakage of a bit-length of the scalar during scalar multiplication is possible on an elliptic curve which might allow practical recovery of the long-term private key.
