Name of the Vulnerable Software and Affected Versions Limit Login Attempts plugin for WordPress versions up to, and including, 1.7.1

Description The issue is related to Stored Cross-Site Scripting via the lock logging feature due to insufficient input sanitization and output escaping. This allows unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever an administrator accesses the plugin's settings page. The vulnerability is exploitable when the plugin prioritizes use of the X-FORWARDED-FOR header, which can be configured in its settings.

Recommendations For versions up to, and including, 1.7.1, update to a version that addresses the insufficient input sanitization and output escaping issue. As a temporary workaround, consider disabling the lock logging feature until a patch is available. Restrict access to the plugin's settings page to minimize the risk of exploitation. Avoid using the X-FORWARDED-FOR header in the plugin's settings until the issue is resolved.
