@adobe/css-tools versions 4.3.1 and earlier are affected by an Improper Input Validation vulnerability that could result in a denial of service while attempting to parse CSS.
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 |
|---|---|---|---|
| Css-tools | Adobe | * | 4.3.2 (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.
