CVE-2026-109191 · Severity: medium · CVSS 4.3 · Published 2026-10-16

The Image Hub plugin for WordPress exposes API credentials for third-party image services (Giphy, Openverse, Pexels, Pixabay, Unsplash) in plain text on admin pages. A subscriber-level user can read these credentials directly from the page HTML and use a leaked AJAX nonce to modify stored API keys without permission, allowing them to redirect image searches or inject malicious content.

## Technical details

The plugin emits API credentials in plaintext into admin page HTML via wp_localize_script() without proper access controls, and also generates a valid AJAX nonce visible to low-privilege users. The image_hub_update_settings AJAX handler lacks capability checks, allowing subscriber-level attackers to call update_option() and overwrite all stored API credentials. Both the information disclosure and the unauthorized settings modification are exploitable by authenticated users with subscriber role or above.
