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.
Weakness
The product uses a regular expression with a worst-case computational complexity that is inefficient and possibly exponential.
