CVE-2026-9019
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe Easy Image Collage plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'grid[properties][borderColor]' and 'grid[images][N][attachment_url]' Parameters in all versions up to, and including, 1.13.6 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Because the data is stored via update_post_meta() rather than wp_insert_post() post content, WordPress's unfiltered_html restriction does not apply, meaning Authors cannot be blocked from this attack path by capability controls alone.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe Easy Image Collage plugin fails to sanitize the grid[properties][borderColor] and grid[images][N][attachment_url] parameters before storage via update_post_meta(), and fails to escape output when rendering. This bypasses WordPress's unfiltered_html capability check since meta data is used instead of post content, allowing author-level attackers to inject persistent JavaScript.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify Easy Image Collage plugin is installedGo to WordPress admin > Plugins and check if 'Easy Image Collage' appears in the installed plugins list. Note the version number displayed under the plugin name.Affected if Plugin is installed and version is 1.13.6 or lower, or version cannot be determined but is known to be below 1.13.7
-
Identify posts using the Easy Image Collage functionalityQuery the WordPress database: SELECT post_id, meta_key, meta_value FROM wp_postmeta WHERE meta_key LIKE '%easy_image_collate%' OR meta_key LIKE '%collage%'. Alternatively, check posts with custom post types if the plugin creates any.Affected if Any posts exist with Easy Image Collage meta data stored, indicating the plugin feature is in use
-
Inspect borderColor parameter in post meta for malicious contentExamine the meta values from the previous step for the grid[properties][borderColor] field. Look for HTML script tags, javascript: URIs, or event handlers like onload, onerror, onclick in the stored value.Affected if The borderColor meta value contains unsanitized HTML, JavaScript code, or event handler attributes
-
Inspect attachment_url parameter in post meta for malicious contentExamine meta values containing grid[images][N][attachment_url] patterns. Check if the URL field contains javascript: protocol or contains HTML tags embedded within the URL value.Affected if Any attachment_url meta value contains javascript: URIs or embedded HTML/script tags
-
Check for unauthorized or suspicious collage postsReview posts created by users with author-level access. Look for collages with unusual content or recently created/modified collages that you did not authorize. Check post_author IDs against expected user accounts.Affected if Collage posts exist that were created by unknown authors or contain unexpected malicious payload content
A user is affected if the Easy Image Collage plugin is installed at version 1.13.6 or below AND any collage posts contain unsanitized script tags, javascript: URIs, or HTML event handlers in the borderColor or attachment_url meta fields.
