CVE-2025-57952 is a medium-severity vulnerability classified as CWE-79, which corresponds to Improper Neutralization of Input During Web Page Generation, commonly known as Cross-site Scripting (XSS). This vulnerability affects the WordPress plugin 'Maps for WP' developed by icopydoc, specifically versions up to and including 1.2.5. The issue allows an attacker to inject malicious scripts that are stored persistently within the application, leading to Stored XSS attacks. Stored XSS occurs when malicious input is saved by the application and later rendered in a victim's browser without proper sanitization or encoding, enabling the attacker to execute arbitrary JavaScript in the context of the victim's session. According to the CVSS v3.1 vector (CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:L), the attack requires network access, low attack complexity, but high privileges and user interaction. The scope is changed, meaning the vulnerability affects resources beyond the initially vulnerable component. The impact on confidentiality, integrity, and availability is low to medium, as the attacker can potentially steal data, manipulate content, or disrupt service to a limited extent. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability is significant because WordPress plugins are widely used to extend website functionality, and a stored XSS in a mapping plugin could be leveraged to target site administrators or users who interact with embedded maps, potentially leading to session hijacking, defacement, or phishing attacks within the affected sites.

For European organizations, this vulnerability poses a risk primarily to websites using the 'Maps for WP' plugin, which may include businesses, local governments, and service providers relying on WordPress for their web presence. Exploitation could lead to unauthorized access to user sessions, data leakage, or injection of malicious content, undermining user trust and potentially violating GDPR requirements related to data protection and breach notification. The requirement for high privileges and user interaction limits the attack surface but does not eliminate risk, especially in environments where multiple users have elevated permissions. Compromise could result in reputational damage, legal consequences, and operational disruptions. Additionally, the cross-site scripting vulnerability could be used as a vector for delivering further malware or conducting targeted attacks against European entities, particularly those with public-facing WordPress sites that incorporate mapping features for customer engagement or information dissemination.

European organizations should take immediate steps to mitigate this vulnerability. First, monitor for updates or patches from the icopydoc vendor and apply them promptly once available. Until a patch is released, restrict plugin usage to trusted administrators and limit the number of users with high privileges to reduce exploitation risk. Implement Web Application Firewalls (WAFs) with rules designed to detect and block XSS payloads targeting the affected plugin. Conduct thorough input validation and output encoding on all user-supplied data related to map inputs or embedded content. Regularly audit WordPress installations and plugins for outdated versions and remove or replace plugins that are no longer maintained or pose security risks. Educate users with elevated privileges about the risks of interacting with untrusted content and the importance of cautious behavior to prevent social engineering attacks. Finally, implement Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers, mitigating the impact of potential XSS attacks.
