The vulnerability identified as CVE-2025-30952 affects the wpdive Nexa Blocks plugin for WordPress, specifically versions up to 1.1.0. It is a stored cross-site scripting (XSS) flaw caused by improper input neutralization during web page generation. This allows an attacker with low privileges to inject malicious scripts that are stored and later executed in the context of users viewing the affected pages. The CVSS 3.1 vector indicates network attack vector, low attack complexity, requiring privileges and user interaction, with impacts on confidentiality, integrity, and availability.

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary scripts in the context of affected users, potentially leading to data disclosure, modification, or disruption of service. The medium severity reflects that exploitation requires some privileges and user interaction, limiting the ease of attack but still posing a risk to affected installations.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should consider restricting privileges to trusted users and be cautious of user-generated content. Monitor vendor communications for updates on patches or official mitigations.
