CVE-2025-12088 is a stored cross-site scripting vulnerability in the Meta Display Block WordPress plugin by bhargavbhandari90. The flaw is due to improper neutralization of input during web page generation (CWE-79), allowing authenticated users with Contributor or higher privileges to inject malicious scripts that execute when the page is viewed. This affects all versions up to 1.0.0. The vulnerability has a CVSS score of 6.4, reflecting a medium severity with network attack vector, low attack complexity, and no user interaction required. The vulnerability impacts confidentiality and integrity but not availability. No patch or official remediation has been provided as of the published date.

An attacker with Contributor-level or higher access can inject malicious scripts into pages via the Meta Display Block plugin. These scripts execute in the context of users viewing the injected pages, potentially leading to unauthorized actions or data exposure limited to the confidentiality and integrity of affected users. There is no reported impact on system availability. The vulnerability requires authenticated access, which limits the attack surface to users with some level of trust on the site.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, site administrators should consider restricting Contributor-level access or disabling the Meta Display Block plugin to prevent exploitation. Monitoring for unusual script injections and reviewing user permissions may help mitigate risk. Avoid granting Contributor or higher privileges to untrusted users.
