CVE-2025-14288: CWE-862 Missing Authorization in gallerycreator Mixed Media Gallery Blocks
The Gallery Blocks with Lightbox. Image Gallery, (HTML5 video , YouTube, Vimeo) Video Gallery and Lightbox for native gallery plugin for WordPress is vulnerable to unauthorized modification of plugin settings in all versions up to, and including, 3.3.0. This is due to the plugin using the `edit_posts` capability check instead of `manage_options` for the `update_option` action type in the `pgc_sgb_action_wizard` AJAX handler. This makes it possible for authenticated attackers, with Contributor-level access and above, to modify arbitrary plugin settings prefixed with `pgc_sgb_*`.
AI Analysis
Technical Summary
The Gallerycreator Mixed Media Gallery Blocks plugin for WordPress (versions up to 3.3.0) suffers from a missing authorization vulnerability (CWE-862). The plugin's AJAX handler 'pgc_sgb_action_wizard' uses the 'edit_posts' capability check to authorize updates to plugin options, which is insufficiently restrictive. As a result, authenticated users with Contributor-level privileges or higher can modify arbitrary plugin settings prefixed with 'pgc_sgb_*'. This vulnerability does not affect confidentiality or availability but impacts integrity by allowing unauthorized modification of plugin settings.
Potential Impact
The vulnerability allows authenticated users with Contributor-level access or higher to modify plugin settings arbitrarily. This could lead to unauthorized changes in the plugin's behavior or configuration, potentially affecting the integrity of the website's media gallery functionality. There is no impact on confidentiality or availability reported. No known exploits are currently in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict Contributor-level access to trusted users only and monitor for suspicious activity related to plugin settings changes. Avoid granting Contributor or higher privileges to untrusted users.
