The ms package before 0.7.1 for Node.js allows attackers to cause a denial of service (CPU consumption) via a long version string, aka a regular expression denial of service (ReDoS).
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 |
|---|---|---|---|
| Ms | Vercel | * | 0.7.1 (excluding) |
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.
