CVE-2026-109191 Details
Description
The Image Hub – Free Images from Unsplash, Pixabay, Pexels, Openverse & Giphy plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 1.2.0 via the 'image_hub_api_keys_* (6 options)' parameter. This makes it possible for authenticated attackers, with subscriber-level access and above, to extract the plaintext API credentials for six third-party services — Giphy, Openverse (client ID and secret), Pexels, Pixabay, and Unsplash — emitted verbatim into every admin page's HTML via wp_localize_script. The leaked page HTML also contains a valid image_hub_nonce AJAX nonce, which — combined with the absence of any capability check in the image_hub_update_settings AJAX handler — allows the same Subscriber-level attacker to overwrite all six stored API credential options via update_option().
A vulnerability allowing sensitive information exposure has been identified in the Image Hub WordPress plugin, specifically in versions through 1.2.0. This vulnerability arises from the 'image_hub_api_keys_*' parameter, which can be exploited by authenticated attackers with subscriber-level access and above. The issue allows for the extraction of plaintext API credentials for Giphy, Openverse (client ID and secret), Pexels, Pixabay, and Unsplash. These credentials are injected directly into the HTML of every admin page via wp_localize_script. Additionally, the exposed HTML includes a valid image_hub_nonce AJAX nonce. This nonce, combined with the lack of capability checks in the image_hub_update_settings AJAX handler, enables a Subscriber-level attacker to overwrite all six API credential options using the update_option() function.
Users are advised to update the Image Hub WordPress plugin to version 1.3.0 or a newer patched version.
