CVE-2024-51622 is a stored cross-site scripting vulnerability found in the WP EASY RECIPE plugin for WordPress, developed by WP-EXPERTS.IN. The vulnerability stems from improper neutralization of user-supplied input during the generation of web pages, allowing malicious scripts to be stored persistently within the plugin's data. When other users or administrators view the affected pages, the injected scripts execute in their browsers, potentially compromising session tokens, cookies, or enabling further attacks such as phishing or malware delivery. The affected versions include all releases up to and including version 1.6. The vulnerability was publicly disclosed on November 9, 2024, but no CVSS score or official patch has been published yet. Stored XSS vulnerabilities are particularly dangerous because they do not require the attacker to trick users into clicking malicious links; the payload is served directly from the compromised site. The plugin is commonly used by WordPress sites focused on food and recipe content, which may have a broad user base including site administrators and visitors. Although no known exploits are currently in the wild, the vulnerability presents a significant risk if weaponized. The lack of a patch means that affected sites remain vulnerable until mitigations or updates are applied. This vulnerability highlights the importance of proper input validation and output encoding in WordPress plugin development to prevent injection attacks.

The impact of CVE-2024-51622 is significant for organizations running WordPress sites with the WP EASY RECIPE plugin. Successful exploitation allows attackers to execute arbitrary JavaScript in the browsers of site visitors or administrators, potentially leading to session hijacking, theft of sensitive information, unauthorized actions performed on behalf of users, defacement, or redirection to malicious websites. This can damage the reputation of affected organizations, lead to data breaches, and compromise user trust. Since the vulnerability is stored XSS, it can affect any user who views the compromised content, increasing the attack surface. E-commerce sites, blogs with user accounts, or sites handling sensitive user data are at higher risk. The absence of a patch increases the window of exposure, making timely mitigation critical. Additionally, attackers could leverage this vulnerability as a foothold for further attacks within the network or to distribute malware. The impact extends beyond individual sites to their users, potentially affecting a wide audience globally.

To mitigate CVE-2024-51622, organizations should first check if an official patch or update from WP-EXPERTS.IN becomes available and apply it immediately. Until then, site administrators should consider disabling or uninstalling the WP EASY RECIPE plugin to eliminate the attack vector. Implementing a Web Application Firewall (WAF) with rules to detect and block XSS payloads can provide temporary protection. Administrators should audit and sanitize existing recipe content and user inputs to remove any malicious scripts. Enforcing Content Security Policy (CSP) headers can help restrict the execution of unauthorized scripts in browsers. Regularly backing up site data and monitoring logs for suspicious activity is recommended. Educating site users and administrators about the risks of XSS and encouraging the use of strong authentication mechanisms can reduce the impact of potential exploitation. Finally, developers should review and improve input validation and output encoding practices in the plugin's codebase to prevent similar vulnerabilities in future releases.
