CVE-2025-39465 is a missing authorization vulnerability identified in the flippercode Advanced Google Maps WordPress plugin (wp-google-map-gold), affecting all versions up to and including 5.8.4. This vulnerability arises from incorrectly configured access control security levels, allowing attackers with low privileges (PR:L) to bypass authorization checks and perform unauthorized actions remotely without requiring user interaction (UI:N). The CVSS 3.1 base score is 8.1, indicating high severity, with a vector indicating network attack vector (AV:N), low attack complexity (AC:L), and no user interaction needed. The vulnerability impacts confidentiality and integrity (C:H/I:H) but does not affect availability (A:N). Exploitation could allow attackers to access or modify sensitive geolocation data or site configurations, potentially leading to data breaches or site defacement. Although no public exploits are currently known, the vulnerability’s nature and ease of exploitation make it a critical concern for WordPress sites using this plugin. The issue was reserved in April 2025 and published in November 2025, but no patch links are currently available, indicating that organizations must monitor for updates or apply interim mitigations.

For European organizations, the impact of CVE-2025-39465 can be significant, especially for those relying on WordPress sites with geolocation or mapping functionalities provided by the Advanced Google Maps plugin. Unauthorized access could lead to exposure or manipulation of sensitive location data, potentially violating GDPR and other data protection regulations. Integrity compromise could result in misinformation or malicious redirection, damaging organizational reputation and trust. Since the vulnerability allows remote exploitation without user interaction, attackers could automate attacks at scale, increasing risk. Organizations in sectors such as logistics, retail, real estate, and public services that use mapping plugins extensively are particularly vulnerable. The lack of availability impact means service disruption is less likely, but data confidentiality and integrity breaches could have long-term consequences including regulatory fines and loss of customer confidence.

Organizations should immediately inventory their WordPress installations to identify the use of the flippercode Advanced Google Maps plugin and its version. Until an official patch is released, restrict access to the plugin’s administrative endpoints using web application firewalls (WAFs) or IP whitelisting to limit exposure. Implement strict role-based access controls within WordPress to minimize the number of users with privileges that could be exploited. Monitor logs for unusual access patterns or unauthorized attempts to access mapping functionalities. Regularly check the vendor’s website and trusted vulnerability databases for patch releases and apply updates promptly. Consider deploying runtime application self-protection (RASP) solutions to detect and block exploitation attempts. Additionally, conduct security awareness training for administrators managing WordPress sites to recognize and respond to suspicious activities related to plugin misuse.
