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 · unedited
The Image Photo Gallery Final Tiles Grid plugin for WordPress is vulnerable to unauthorized access and modification of data due to missing capability checks on multiple AJAX actions in all versions up to, and including, 3.6.9. This makes it possible for authenticated attackers, with Contributor-level access and above, to view, create, modify, clone, delete, and reassign ownership of galleries created by other users, including administrators.

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 · moderate confidence

The Image Photo Gallery Final Tiles Grid WordPress plugin lacks proper capability checks on AJAX action handlers, allowing any authenticated user with Contributor-level access or higher to view, create, modify, clone, delete, and reassign ownership of galleries created by other users (including administrators) by manipulating gallery IDs in requests.

MitigationUpdate to a patched version of the plugin once available. Until then, restrict user registration to trusted roles only, or disable the plugin if not essential.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Confirm plugin installation
    Navigate to WordPress admin > Plugins and verify 'Image Photo Gallery Final Tiles Grid' is installed and active
    Affected if Plugin is not installed or not active - not affected
  2. Identify installed version
    In Plugins list, locate the plugin and note the version number displayed beneath the plugin name
    Affected if Version is unknown or falls below the patched version - potentially affected
  3. Check user registration status
    Go to WordPress admin > Settings > General and look for the 'Membership' setting 'Anyone can register' - verify whether this is enabled
    Affected if Anyone can register is enabled - highly vulnerable to exploitation
  4. Audit contributor-level users
    Go to WordPress admin > Users and list all users with Contributor, Author, Editor, or Administrator roles; identify any accounts not fully trusted
    Affected if Untrusted or external users have Contributor-level access or higher - vulnerable to IDOR attacks

The environment is affected if the plugin is installed with an unpatched version AND user registration is open OR untrusted accounts possess Contributor-level or higher access.

Generated from the published advisory. Verify against your own configuration.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

Mitigation

Update to a patched version of the plugin once available. Until then, restrict user registration to trusted roles only, or disable the plugin if not essential.

Recommended fix Moderate confidence

Latest version of Image Photo Gallery Final Tiles Grid plugin (version higher than 3.6.9)

  1. 1. Log in to the WordPress admin dashboard
  2. 2. Navigate to Plugins > Installed Plugins
  3. 3. Locate the 'Image Photo Gallery Final Tiles Grid' plugin
  4. 4. Check if an update is available for the plugin
  5. 5. If an update is available, update the plugin to the latest version (a version higher than 3.6.9)
