CVE-2025-8619 identifies a stored Cross-Site Scripting (XSS) vulnerability within the OSM Map Widget for Elementor, a plugin widely used in WordPress sites to embed OpenStreetMap maps. The vulnerability stems from improper neutralization of input during web page generation (CWE-79), specifically due to inadequate sanitization and escaping of user-supplied data in the Map Block URL attribute. This flaw allows authenticated users with contributor-level permissions or higher to inject arbitrary JavaScript code into pages. When other users access these pages, the malicious scripts execute in their browsers, potentially leading to theft of session cookies, defacement, or further exploitation. The vulnerability affects all plugin versions up to and including 1.3.0. The attack vector is remote over the network, with low attack complexity and no user interaction required beyond authentication. The scope is changed because injected scripts can affect other users viewing the compromised pages. The CVSS 3.1 base score is 6.4, indicating medium severity, with impacts on confidentiality and integrity but no impact on availability. No patches or fixes are currently linked, and no known exploits have been reported in the wild as of the publication date. The vulnerability was publicly disclosed on August 29, 2025, with the initial reservation on August 5, 2025.

The primary impact of this vulnerability is the potential compromise of user confidentiality and integrity on WordPress sites utilizing the affected OSM Map Widget plugin. Attackers with contributor-level access can inject malicious scripts that execute in the browsers of site visitors or administrators, enabling session hijacking, credential theft, unauthorized actions performed on behalf of users, or distribution of malware. This can lead to defacement, data leakage, or further compromise of the website and its users. Since the vulnerability requires authentication, the risk is somewhat mitigated but remains significant in environments where contributor or higher roles are assigned to multiple users or where accounts may be compromised. The vulnerability does not affect availability directly but can indirectly cause reputational damage and loss of user trust. Organizations relying on this plugin for map embedding in WordPress sites are at risk, especially those with high traffic or sensitive user data. The absence of known exploits in the wild reduces immediate risk but does not preclude future exploitation.

To mitigate CVE-2025-8619, organizations should first check for and apply any official patches or updates from the plugin vendor once available. In the absence of patches, administrators should restrict contributor-level access to trusted users only and audit existing user roles to minimize exposure. Implementing a Web Application Firewall (WAF) with custom rules to detect and block suspicious script injection attempts in the Map Block URL parameter can provide interim protection. Site owners should also enable Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts. Regularly scanning the website for injected scripts or anomalous content is advised. Additionally, educating contributors on safe input practices and monitoring logs for unusual activity can help detect exploitation attempts early. If feasible, temporarily disabling or replacing the vulnerable plugin with a secure alternative until a fix is released is recommended.
