The vulnerability CVE-2025-58790 in WPKube Kiwi's kiwi-social-share component is a stored cross-site scripting (XSS) issue caused by improper input neutralization during web page generation. This allows attackers to inject malicious scripts that persist and execute in the context of users visiting affected pages. The issue affects all versions up to 2.1.8. The CVSS 3.1 vector indicates network attack vector, low attack complexity, requiring low privileges and user interaction, with a scope change and limited impact on confidentiality, integrity, and availability. No patch or vendor advisory information is currently available, and no exploits are known in the wild.

Successful exploitation of this stored XSS vulnerability could allow an attacker to execute arbitrary scripts in the context of users' browsers, potentially leading to session hijacking, defacement, or other malicious actions affecting confidentiality, integrity, and availability to a limited degree. The medium CVSS score reflects these impacts. No known active exploitation has been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, users should consider restricting privileges and limiting user input where possible. Monitor official WPKube channels for updates and apply patches promptly once released.
