CVE-2025-23995

Vulnerability

Description

The Tantyyellow WordPress theme, through version 1.0.0.5, contains a reflected cross-site scripting (XSS) vulnerability stemming from improper neutralization of user-supplied input during web page generation [1]. This flaw enables an attacker to inject arbitrary HTML and JavaScript into web pages rendered by the theme.

Exploitation

Prerequisites

Exploitation requires user interaction: a victim must click a crafted link, visit a maliciously prepared page, or submit a specially designed form [1]. The attack does not require authentication but relies on tricking a privileged user (e.g., an administrator) into performing an action, making it a medium-complexity attack vector.

Impact

A successful attack allows the adversary to inject malicious scripts that execute when other visitors access the affected site [1]. Common payloads include redirects to external domains, unwanted advertisements, or other HTML content that compromises the integrity of the website and can lead to further attacks against site visitors.

Mitigation

Status

No official patch has been released as of the publication date. Patchstack has issued a mitigation rule to block attacks until a full fix can be tested and safely applied [1]. Administrators are urged to update the theme immediately when a patch becomes available or contact their hosting provider for assistance [1].
