The WPZOOM Portfolio Lite – Filterable Portfolio Plugin for WordPress suffers from a stored cross-site scripting vulnerability (CWE-79) due to improper neutralization of input in the 'align' attribute of the 'wp:wpzoom-blocks' Gutenberg block. This allows authenticated users with at least Contributor privileges to inject arbitrary JavaScript code that executes in the context of users viewing the injected content. The vulnerability affects all versions up to 1.4.4. The CVSS 3.1 base score is 6.4, reflecting network attack vector, low attack complexity, privileges required, no user interaction, and partial impact on confidentiality and integrity but no impact on availability. No patch or vendor advisory is currently provided, and no known exploits have been reported.

An attacker with Contributor-level or higher access can inject persistent malicious scripts into pages via the vulnerable 'align' attribute. These scripts execute in the browsers of users who view the compromised pages, potentially leading to unauthorized actions or data disclosure limited to the scope of the injected script. The vulnerability does not impact availability. The medium CVSS score reflects the moderate risk posed by this vulnerability in environments where untrusted contributors exist.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict Contributor-level access to trusted users only and consider removing or disabling the WPZOOM Portfolio Lite – Filterable Portfolio Plugin if possible. Monitor vendor channels for updates and apply patches promptly once available.
