An exponential ReDoS (Regular Expression Denial of Service) can be triggered in the devcert npm package, when an attacker is able to supply arbitrary input to the certificateFor method
The product uses a regular expression with an inefficient, possibly exponential worst-case computational complexity that consumes excessive CPU cycles.

Attackers can create crafted inputs that
intentionally cause the regular expression to use
excessive backtracking in a way that causes the CPU
consumption to spike.
