The vulnerability CVE-2025-31025 affects the Blocksera Image Hover Effects Block plugin (up to version 1.4.5). It is a stored cross-site scripting (XSS) issue caused by improper neutralization of input during web page generation. An attacker with low privileges can inject malicious scripts that are stored and later executed in the context of other users who view the affected content. The CVSS 3.1 base score is 6.5, reflecting network attack vector, low attack complexity, requiring privileges and user interaction, with impacts on confidentiality, integrity, and availability.

Successful exploitation could allow an attacker to execute arbitrary scripts in the context of users viewing the affected content, potentially leading to information disclosure, modification of data, or disruption of service. The vulnerability requires low privileges and user interaction but can impact multiple security properties (confidentiality, integrity, availability). No known active exploitation has been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
