CVE-2024-8730 is a reflected Cross-Site Scripting vulnerability in the WordPress Exit Notifier plugin by cvscvstechcom. The issue stems from the use of add_query_arg without proper escaping of URL parameters, which allows injection of malicious scripts. This affects all versions up to and including 1.10.4. An attacker can exploit this by crafting a URL that, when clicked by a user, executes arbitrary JavaScript in the context of the affected site. The vulnerability has a CVSS 3.1 base score of 6.1 (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N), indicating network attack vector, low attack complexity, no privileges required, user interaction required, scope changed, with low confidentiality and integrity impact and no availability impact. There is no vendor-provided patch or advisory available at this time.

Successful exploitation can lead to execution of arbitrary scripts in the context of the affected website, potentially allowing attackers to steal user session data, perform actions on behalf of the user, or conduct phishing attacks. The impact is limited to confidentiality and integrity with no availability impact. The vulnerability requires user interaction (clicking a malicious link) and does not require authentication.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should avoid clicking suspicious links related to the affected plugin and consider disabling or removing the Exit Notifier plugin if possible.
