All versions of `eco` are vulnerable to Cross-Site Scripting (XSS). The package's default `__escape` implementation fails to escape single quotes, which may allow attackers to execute arbitrary JavaScript on the victim's browser.

## Recommendation

No fix is currently available. Consider using an alternative package until a fix is made available.
