CVE-2026-109191

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().
