WordPress vulnerability analysis and mitigation

A Cross-Site Scripting (XSS) vulnerability has been identified in the WordPress RDFa Breadcrumb plugin, tracked as CVE-2025-50020. The vulnerability was discovered by Nabil Irawan and affects versions up to 2.3 of the plugin. The issue was reported on May 18, 2025, and publicly disclosed on June 19, 2025. The vulnerability specifically involves improper neutralization of input during web page generation, allowing for stored XSS attacks (Wiz, NVD).

The vulnerability has been assigned a CVSS v3.1 base score of 5.9 (Medium) with the vector string CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:L. The technical classification falls under CWE-79: Improper Neutralization of Input During Web Page Generation. Administrator privileges are required to exploit this vulnerability (Wiz, Patchstack).

The vulnerability allows malicious actors to inject malicious scripts, including redirects, advertisements, and other HTML payloads into the website. These injected scripts will be executed when visitors access the affected site. The impact is considered low severity but could affect website integrity and user experience (Wiz).

No official fix is currently available for this vulnerability. The software is considered abandoned as it hasn't been updated for over a year. The recommended mitigation strategy is to remove and replace the plugin with an alternative solution. Deactivating the software alone does not remove the security threat unless a virtual patch is deployed (Wiz).
