CVE-2025-25164

Vulnerability

Type and Root Cause

CVE-2025-25164 is a reflected cross-site scripting (XSS) vulnerability in the WordPress plugin Meta Accelerator, affecting versions from n/a through 1.0.4. The root cause is an improper neutralization of user-supplied input during web page generation [1]. This allows an attacker to inject arbitrary HTML and JavaScript code into the application's response, which is then executed in the user's browser.

Exploitation

Prerequisites and Attack Vector

Exploitation requires user interaction. The attacker must trick a logged-in user (such as an administrator or editor) into clicking a crafted link, visiting a specially prepared page, or submitting a malicious form [1]. The attack does not require any special network access beyond typical web interactions. The reflected nature of the vulnerability means the injected payload is part of the request and immediately echoed back in the response.

Impact on

Affected Systems

Successful exploitation could allow an attacker to inject malicious scripts — including redirects, advertisements, and other HTML payloads — into the website [1]. These payloads execute when other users visit the affected site, potentially leading to session hijacking, defacement, or further compromise of victim browsers.

Mitigation and

Remediation Status

No official patch was available at the time of disclosure. The vendor or Patchstack has issued a mitigation rule to block attacks until an official fix can be tested and safely applied [1]. Users are strongly advised to update the plugin immediately, or contact their hosting provider for assistance if updating is not possible [1]. The vulnerability is considered moderately dangerous and is expected to be used in mass-exploit campaigns.
