CVE-2025-8624: 
WordPress vulnerability analysis and mitigation

The Nexa Blocks plugin for WordPress contains a Stored Cross-Site Scripting vulnerability (CVE-2025-8624) in its Google Maps widget component. This vulnerability affects all versions up to and including 1.1.0. The issue was discovered and reported by security researcher zer0gh0st, with public disclosure on September 29, 2025 (NVD, Wordfence).

The vulnerability stems from insufficient input sanitization and output escaping on user-supplied attributes in the Google Maps widget component. The issue has been assigned a CVSS v3.1 score of 6.4 (Medium) with the vector string CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N. The vulnerability is classified as CWE-79 (Improper Neutralization of Input During Web Page Generation) (NVD).

When exploited, this vulnerability allows authenticated attackers with contributor-level access or higher to inject arbitrary web scripts into pages. These malicious scripts will execute whenever any user accesses the compromised page, potentially leading to data theft, session hijacking, or other client-side attacks (NVD).

As of September 26, 2025, the plugin has been temporarily closed and is not available for download pending a full security review (WordPress). Site administrators using affected versions should consider disabling the plugin until a patched version is released.
