CVE-2024-56292 is a stored cross-site scripting vulnerability found in the wpdevelop Email Reminders plugin for WordPress, affecting versions up to and including 2.0.5. The vulnerability stems from improper neutralization of user-supplied input during web page generation, which allows malicious scripts to be stored persistently within the application. When an authenticated user or administrator views the affected page or email content, the malicious script executes in their browser context. This can lead to a range of attacks including session hijacking, theft of sensitive information, unauthorized actions performed on behalf of the user, and potential malware distribution. The plugin is designed to send email reminders, and the vulnerability likely arises from insufficient sanitization of input fields that are later rendered in HTML content. No CVSS score has been assigned yet, and no public exploits have been reported, but the vulnerability is publicly disclosed and considered serious due to the stored nature of the XSS and the potential impact on user sessions and data integrity. The issue affects all versions up to 2.0.5, and users are advised to monitor for patches or updates from the vendor. The vulnerability was reserved in December 2024 and published in January 2025, indicating recent discovery and disclosure.

The impact of CVE-2024-56292 is significant for organizations using the vulnerable Email Reminders plugin on WordPress sites. Stored XSS vulnerabilities allow attackers to inject malicious scripts that execute in the browsers of users who view the compromised content, potentially leading to session hijacking, credential theft, unauthorized actions, and spread of malware. This can result in data breaches, loss of user trust, and compromise of administrative accounts. Since the plugin is used for email reminders, the attack surface may include both website administrators and end users receiving or interacting with reminder content. The vulnerability can disrupt business operations, especially for organizations relying on WordPress for customer engagement and communication. The absence of known exploits currently limits immediate widespread impact, but the ease of exploitation and persistence of stored XSS make it a high-risk issue if weaponized. Organizations with high-value targets or sensitive data hosted on WordPress platforms are particularly at risk.

1. Monitor for and apply official patches or updates from wpdevelop as soon as they are released to remediate the vulnerability. 2. Until patches are available, implement strict input validation and sanitization on all user-supplied data fields related to email reminders, ensuring that HTML special characters are properly encoded before rendering. 3. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers. 4. Conduct regular security audits and code reviews of plugins and custom code to detect similar input validation issues. 5. Limit plugin usage to trusted and actively maintained components, and consider alternative plugins with better security track records if timely patches are not forthcoming. 6. Educate administrators and users about the risks of XSS and encourage cautious interaction with unexpected or suspicious content. 7. Use web application firewalls (WAFs) with rules designed to detect and block XSS payloads targeting WordPress plugins.
