Overview
Affected versions of this package are vulnerable to Improper Input Validation due to the this.lastSegment variable in the emit function not being sanitized. An attacker can manipulate the this.lastSegment variable to set it to __proto__, leading to prototype pollution.
Notes:
1)If the application author has atypical HTML templates that feed user input into an object key.
- Attribute keys are almost always developer-controlled, not end-user-controlled, so this shouldn't be an issue in practice for most applications.
