The Denosaurs emoji package provides emojis for dinosaurs. Starting in version 0.1.0 and prior to version 0.3.0, the reTrimSpace regex has 2nd degree polynomial inefficiency, leading to a delayed response given a big payload. The issue has been patched in 0.3.0. As a workaround, avoid using the replace, unemojify, or strip functions.
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 |
|---|---|---|---|
| Emoji | Denosaurs | 0.1.0 (including) | 0.3.0 (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.
