CVE-2026-9019 · Severity: medium · CVSS 6.4 · Published 2026-06-10

The Easy Image Collage plugin for WordPress, which allows users to create custom image layouts, contains a security flaw that allows users with 'Author' permissions or higher to inject malicious scripts into website pages. These scripts execute automatically when other users visit the affected pages, potentially leading to unauthorized actions or data theft. This vulnerability is particularly significant because it bypasses standard WordPress security restrictions that normally prevent authors from adding such scripts.

## Technical details

The Easy Image Collage plugin for WordPress is vulnerable to Stored Cross-Site Scripting (XSS) due to insufficient input sanitization and output escaping on the 'grid[properties][borderColor]' and 'grid[images][N][attachment_url]' parameters. An authenticated attacker with Author-level permissions or higher can inject arbitrary web scripts into post metadata. Because the plugin utilizes update_post_meta() instead of wp_insert_post(), it bypasses the standard WordPress unfiltered_html security restriction. This allows the stored script to execute in the context of any user visiting the page. The issue is addressed in version 2.0.0.
