CVE-2025-58883

Vulnerability

Overview

The Search Cloud One plugin for WordPress versions up to and including 2.2.5 suffers from a stored cross-site scripting (XSS) vulnerability due to improper neutralization of user-supplied input during web page generation [1]. This flaw enables an attacker to inject arbitrary JavaScript or HTML into the plugin's output, which is then stored and executed in the context of the victim's browser.

Exploitation

Details

Exploitation requires a privileged user (e.g., an administrator) to perform an action such as clicking a crafted link, visiting a malicious page, or submitting a specially crafted form [1]. The attacker does not need direct access to the site but must convince a user with the appropriate role to trigger the payload. The vulnerability is particularly dangerous because it can be used in mass-exploit campaigns targeting thousands of WordPress sites regardless of their size or popularity [1].

Impact

Successful exploitation allows the attacker to inject malicious scripts that execute when any visitor loads the affected page [1]. This can lead to redirects to malicious sites, injection of advertisements, theft of session cookies, or other harmful actions that compromise the integrity and security of the website and its visitors.

Mitigation

As an immediate action, users should update the Search Cloud One plugin to a version newer than 2.2.5 [1]. If updating is not possible, it is recommended to contact the hosting provider or a web developer for assistance. No workarounds are provided by the vendor, and the vulnerability is listed in Patchstack's database with a CVSS score of 5.9 (Medium).
