CVE-2026-109191

MediumCVSS 4.3
Published: Translated: NVD NIST

Summary

The Image Hub – Free Images from Unsplash, Pixabay, Pexels, Openverse & Giphy plugin for WordPress in versions up to and including 1.2.0 is vulnerable to Sensitive Information Exposure via the 'image_hub_api_keys_* (6 options)' parameter. An authenticated attacker with subscriber-level access and above can extract 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 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 attacker to overwrite all six stored API credential options via update_option().

Risk Assessment

An attacker can obtain and overwrite third-party API keys, potentially leading to unauthorized service use and further compromise.

Recommendation

Update the Image Hub plugin to a version later than 1.2.0. Consider rotating the exposed API keys.
