CVE-2025-62904 identifies a stored Cross-site Scripting (XSS) vulnerability in the WP Geo plugin for WordPress, developed by Ben Huson. The vulnerability stems from improper neutralization of user-supplied input during the generation of web pages, allowing attackers to inject malicious JavaScript code that is stored persistently within the application. When other users or administrators view the affected pages, the malicious script executes in their browsers, potentially leading to session hijacking, unauthorized actions, or redirection to malicious websites. The vulnerability affects all versions of WP Geo up to and including 3.5.1. Exploitation does not require authentication or user interaction beyond visiting a compromised page, increasing the risk profile. Although no public exploits have been reported yet, the nature of stored XSS makes it a critical concern for websites relying on this plugin. WP Geo is commonly used to add geolocation features to WordPress sites, which are prevalent in many European organizations. The lack of a CVSS score indicates that the vulnerability is newly published, but based on its characteristics, it poses a significant threat to confidentiality and integrity of affected web applications. The vulnerability was reserved and published in late October 2025, with no patch currently available, highlighting the need for immediate attention from site administrators.

For European organizations, the stored XSS vulnerability in WP Geo can lead to severe consequences including theft of user credentials, unauthorized actions performed with the privileges of authenticated users, defacement of websites, and distribution of malware through malicious redirects. Organizations in sectors such as government, media, e-commerce, and any business relying on WordPress for customer engagement or internal portals are particularly vulnerable. The compromise of user sessions can lead to data breaches involving personal data protected under GDPR, resulting in regulatory penalties and reputational damage. Additionally, the persistent nature of stored XSS increases the attack surface and duration of exposure. Since WP Geo is a plugin that enhances geolocation capabilities, organizations using location-based services may face targeted attacks exploiting this vulnerability to manipulate location data or track users. The lack of a patch at the time of disclosure means organizations must implement interim mitigations to reduce risk. The impact on availability is generally low, but the integrity and confidentiality risks are high, especially if administrative accounts are targeted.

1. Monitor the official WP Geo plugin repository and vendor announcements closely for the release of a security patch addressing CVE-2025-62904 and apply it immediately upon availability. 2. Until a patch is released, implement strict input validation and output encoding on all user-supplied data fields related to WP Geo, either via custom code or security plugins that sanitize inputs and outputs. 3. Deploy a Content Security Policy (CSP) that restricts the execution of inline scripts and limits sources of executable scripts to trusted domains to mitigate the impact of injected scripts. 4. Conduct a thorough audit of all stored content generated by WP Geo to identify and remove any malicious scripts that may have been injected prior to mitigation. 5. Restrict administrative access to the WordPress backend to trusted IP addresses and enforce multi-factor authentication to reduce the risk of session hijacking. 6. Regularly back up website data and configurations to enable quick restoration in case of compromise. 7. Educate site administrators and users about the risks of XSS and encourage vigilance for suspicious site behavior or unexpected redirects. 8. Consider temporarily disabling the WP Geo plugin if it is not critical to operations until a secure version is available.
