The package react-native-reanimated before 3.0.0-rc.1 are vulnerable to Regular Expression Denial of Service (ReDoS) due to improper usage of regular expression in the parser of Colors.js.
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 |
|---|---|---|---|
| React_native_reanimated | Swmansion | * | 2.10.0 (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.
