XSS in Automattic Limit Login Attempts
CVE-2023-1912
The Limit Login Attempts plugin for WordPress is vulnerable to Stored Cross-Site Scripting via its lock logging feature in versions up to, and including, 1.7.1 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever an administrator accesses the plugin's settings page. This only works when the plugin prioritizes use of the X-FORWARDED-FOR header, which can be configured in its settings.
