CVE-2024-12475 is a stored Cross-Site Scripting (XSS) vulnerability identified in the WP Multi Store Locator plugin for WordPress, affecting all versions up to and including 2.4.1. The vulnerability stems from improper neutralization of input during web page generation (CWE-79), where the plugin fails to adequately sanitize user-supplied input and escape output before rendering it on web pages. This flaw allows authenticated attackers with Contributor-level access or higher to inject arbitrary JavaScript code into pages managed by the plugin. Because the malicious scripts are stored persistently, they execute in the context of any user who views the compromised page, potentially leading to session hijacking, credential theft, or unauthorized actions performed on behalf of users. The CVSS 3.1 base score of 6.4 reflects a medium severity, with an attack vector over the network, low complexity, privileges required at the contributor level, no user interaction needed, and a scope change indicating that the vulnerability affects components beyond the initially vulnerable plugin. The vulnerability impacts confidentiality and integrity but does not affect availability. No public exploits have been reported yet, but the presence of this vulnerability in a popular WordPress plugin used for store location management makes it a significant risk for websites relying on this functionality. The lack of official patches at the time of disclosure necessitates immediate mitigation efforts by site administrators.

The exploitation of CVE-2024-12475 can have several adverse effects on organizations worldwide. Attackers can leverage the stored XSS vulnerability to execute arbitrary scripts in the browsers of users visiting affected pages, leading to theft of session cookies, user credentials, or other sensitive information. This can result in unauthorized access to user accounts or administrative functions, data leakage, and potential site defacement. For e-commerce or multi-store websites, this can damage customer trust and lead to financial losses. The vulnerability's ability to affect multiple users without requiring their interaction increases its risk profile. Additionally, attackers could use the vulnerability as a foothold for further attacks within the network or to distribute malware. Organizations with Contributor-level users who may not be fully trusted or monitored are particularly at risk. The medium severity score indicates a significant but not critical threat, yet the widespread use of WordPress and this plugin amplifies the potential impact globally.

To mitigate CVE-2024-12475 effectively, organizations should: 1) Immediately restrict Contributor-level user privileges to trusted personnel only, minimizing the risk of malicious script injection. 2) Monitor and audit user-generated content within the WP Multi Store Locator plugin for suspicious or unauthorized script tags or payloads. 3) Deploy a Web Application Firewall (WAF) with rules specifically designed to detect and block XSS payloads targeting WordPress plugins. 4) Implement Content Security Policy (CSP) headers to limit the execution of unauthorized scripts on affected pages. 5) Regularly back up website data to enable quick restoration if compromise occurs. 6) Stay alert for official patches or updates from the plugin vendor and apply them promptly once available. 7) Consider temporarily disabling or replacing the WP Multi Store Locator plugin if immediate patching is not feasible. 8) Educate users with elevated privileges about secure content management practices and the risks of injecting untrusted code. These steps go beyond generic advice by focusing on access control, monitoring, and layered defenses tailored to this specific vulnerability.
