CVE-2025-6588: 
WordPress vulnerability analysis and mitigation

CVE-2025-6588 affects the FunnelCockpit plugin for WordPress in versions up to and including 1.4.2. The vulnerability was discovered and disclosed on July 24, 2025, and is identified as a Reflected Cross-Site Scripting (XSS) vulnerability that exists due to insufficient input sanitization and output escaping of the 'error' parameter (NVD).

The vulnerability is classified as CWE-79 (Improper Neutralization of Input During Web Page Generation) with a CVSS v3.1 Base Score of 6.1 (Medium). The attack vector is network-based (AV:N), with low attack complexity (AC:L), requires no privileges (PR:N), and needs user interaction (UI:R). The scope is changed (S:C), with low confidentiality (C:L) and integrity (I:L) impacts, and no availability impact (A:N) (NVD).

If successfully exploited, this vulnerability allows unauthenticated attackers to inject arbitrary web scripts that execute when administrative users perform specific actions, such as clicking on a malicious link. This could potentially lead to the compromise of administrative user sessions and unauthorized actions being performed on the WordPress installation (NVD).

Users should update the FunnelCockpit plugin to a version newer than 1.4.2 when available. Until a patch is released, administrators should exercise caution when clicking on links while logged into WordPress and consider disabling the plugin if it's not critical to operations (NVD).
