|

|
||||
The OWASP Top 10 web security risks study lists Cross-Site Scripting (XSS) in
|
||||
second place. PHP’s sole functionality against XSS is limited to two functions
|
||||
of which one is commonly misapplied. Thus, the laminas-escaper component was written.
|
||||
It offers developers a way to escape output and defend from XSS and related
|
||||
vulnerabilities by introducing contextual escaping based on peer-reviewed rules.
|
||||
|
||||
## Installation
|
||||
|
||||
Run the following to install this library:
|
||||
|
||||
```bash
|
||||
$ composer require laminas/laminas-escaper
|
||||
```
