CVE-2025-58227: 
WordPress vulnerability analysis and mitigation

A Stored Cross-Site Scripting (XSS) vulnerability was identified in the Podlove Subscribe button WordPress plugin, tracked as CVE-2025-58227. The vulnerability was discovered on July 31, 2025, and publicly disclosed on September 22, 2025. This security issue affects all versions of the Podlove Subscribe button plugin through version 1.3.11, developed by Alexander Lueken (Patchstack).

The vulnerability is classified as CWE-79 (Improper Neutralization of Input During Web Page Generation) and has received a CVSS v3.1 score of 6.5 (Medium). The attack vector is network-based (AV:N) with low attack complexity (AC:L), requiring low privileges (PR:L) and user interaction (UI:R). The scope is changed (S:C) with low impacts on confidentiality, integrity, and availability (C:L/I:L/A:L) (NVD, Patchstack).

The vulnerability allows malicious actors to inject malicious scripts, including redirects, advertisements, and other HTML payloads into the website. These injected scripts are executed when visitors access the affected site. The plugin is considered abandoned, as it hasn't received updates for over a year, increasing the security risk for websites using this software (Patchstack).

As no official fix is available and the software is considered abandoned, 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 additional protective measures are implemented (Patchstack).
