CVE-2025-48107

Vulnerability

Description The Uncode WordPress theme, before version 2.9.4.4, contains a reflected Cross-Site Scripting (XSS) vulnerability due to improper neutralization of user input during web page generation [1]. This flaw stems from insufficient sanitization of parameters that are reflected back in the response, enabling attackers to inject malicious scripts into otherwise trusted web pages.

Exploitation

Prerequisites Exploitation of this vulnerability requires user interaction—a privileged user must click a crafted link, visit a specially prepared page, or submit a malicious form [1]. No authentication is required from the attacker, but the target user needs to have at least some privileges (though the exact role is not specified). The attack vector is network-based, and the complexity is low, as confirmed by the CVSS score of 7.1 [1].

Impact

Successful exploitation allows an attacker to execute arbitrary scripts in the context of the target user's browser session. This can lead to session hijacking, redirection to malicious sites, defacement, or other actions that could compromise the website's security and user trust [1]. The vulnerability is considered moderately dangerous and is expected to be used in mass-exploit campaigns targeting many websites simultaneously.

Mitigation

The vendor has released a patched version 2.9.4.4 to resolve the issue [1]. Users are advised to update immediately. For those unable to update, Patchstack provides a mitigation rule that blocks attacks until the update is applied. The vulnerability is tracked and customers of Patchstack receive real-time protection [1].
