Inefficient Regular Expression Complexity in GitHub repository node-fetch/node-fetch prior to 3.2.10.
The product uses a regular expression with an inefficient, possibly exponential worst-case computational complexity that consumes excessive CPU cycles.
| Name | Vendor | Start Version | End Version |
|---|---|---|---|
| Node-fetch | Node-fetch_project | 3.0.0 (including) | 3.2.10 (excluding) |
| Node-fetch | Ubuntu | bionic | * |
| Node-fetch | Ubuntu | kinetic | * |
| Node-fetch | Ubuntu | lunar | * |
| Node-fetch | Ubuntu | mantic | * |
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.
