CVE-2025-48151 is a high-severity reflected Cross-Site Scripting (XSS) vulnerability identified in the CreativeMindsSolutions CM Map Locations plugin, affecting versions up to 2.1.6. This vulnerability arises due to improper neutralization of user-supplied input during web page generation, classified under CWE-79. Reflected XSS occurs when malicious scripts injected via crafted URLs or input fields are immediately reflected back in the HTTP response without proper sanitization or encoding, allowing attackers to execute arbitrary JavaScript in the context of the victim's browser. The CVSS 3.1 base score of 7.1 reflects the vulnerability's characteristics: it is remotely exploitable over the network (AV:N), requires no privileges (PR:N), but does require user interaction (UI:R), and impacts confidentiality, integrity, and availability to a limited extent (C:L/I:L/A:L). The scope is changed (S:C), indicating that exploitation can affect resources beyond the vulnerable component. Although no known exploits are currently reported in the wild, the vulnerability poses a significant risk, especially in environments where the plugin is used to display location data dynamically on web pages. Attackers could leverage this flaw to steal session cookies, perform actions on behalf of authenticated users, or redirect users to malicious sites, potentially leading to account compromise or broader network intrusion.

For European organizations, the impact of this vulnerability can be substantial, particularly for entities relying on the CM Map Locations plugin to provide interactive geographic data on their websites. Exploitation could lead to unauthorized access to user sessions, data leakage, and manipulation of web content, undermining user trust and violating data protection regulations such as GDPR. Organizations in sectors like tourism, logistics, real estate, and local government that use this plugin to display location-based information are at heightened risk. The reflected XSS can facilitate phishing attacks or malware distribution targeting European users, potentially causing reputational damage and financial losses. Additionally, the cross-site scripting vulnerability could be chained with other exploits to escalate privileges or move laterally within an organization's network, increasing the overall threat landscape.

To mitigate this vulnerability, European organizations should prioritize updating the CM Map Locations plugin to a patched version once available from CreativeMindsSolutions. In the absence of an official patch, organizations should implement strict input validation and output encoding on all user-supplied data, especially parameters reflected in web pages. Employing Content Security Policy (CSP) headers can help restrict the execution of unauthorized scripts. Web Application Firewalls (WAFs) should be configured to detect and block typical XSS attack patterns targeting the plugin's endpoints. Regular security audits and penetration testing focusing on web input handling can identify residual injection points. Additionally, educating users about the risks of clicking on suspicious links and monitoring web logs for anomalous requests can aid in early detection and response. Organizations should also review their incident response plans to address potential XSS exploitation scenarios effectively.
