At a glance
CVE-2024-6224 is a medium-severity Cross-Site Request Forgery (CSRF) vulnerability in the Send email only on Reply to My Comment WordPress plugin, affecting versions <= 1.0.6. It carries a CVSS score of 6.1 (reachable over the network; low attack complexity). Exploitation requires no authentication. No fixed release has been reported yet; treat installations running this software as exposed. Disclosed July 2024, reported by Bob Matyas.
Vulnerability Overview
The Send email only on Reply to My Comment plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.0.6. This is due to missing or incorrect nonce validation on the subscribe_reloaded_update_option() function. This makes it possible for unauthenticated attackers to update the plugin's settings and inject malicious web scripts via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site.
CWE-352: Cross-Site Request Forgery (CSRF)
Send email only on Reply to My Comment <= 1.0.6 carries this weakness at subscribe_reloaded_update_option(), and reaching it takes a caller who can reach the endpoint. Cross-site request forgery abuses the fact that browsers attach a victim's cookies to any request, so a state-changing action that only checks who you are, not whether you meant to act, can be triggered from another site.
An attacker who gets a logged-in user to load a crafted page can perform that action as them, with the impact scaling to whatever the victim's role is allowed to do. No fixed build of this plugin is recorded for Send email only on Reply to My Comment yet, so installs running <= 1.0.6 stay exposed until the vendor ships one.
Remediation
No known patch available. Please review the vulnerability's details in depth and employ mitigations based on your organization's risk tolerance. It may be best to uninstall the affected software and find a replacement.
