Low risk5th percentile - higher than 5% of all known CVEs
Summary
The USS Upyun plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.5.0. This is due to missing or incorrect nonce validation on the uss_setting_page function when processing the uss_set form type. Unauthenticated attackers can modify critical Upyun cloud storage settings including bucket name, operator credentials, upload paths, and image processing parameters via a forged request if they trick a site administrator into clicking a link.
Risk Assessment
An attacker can alter critical Upyun cloud settings, potentially leading to data leakage, unauthorized access, or configuration corruption.
Recommendation
Update the USS Upyun plugin to a version later than 1.5.0 or remove it if not in use.

Original NVD description (English source)
The USS Upyun plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.5.0. This is due to missing or incorrect nonce validation on the uss_setting_page function when processing the uss_set form type. This makes it possible for unauthenticated attackers to modify critical Upyun cloud storage settings including bucket name, operator credentials, upload paths, and image processing parameters via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
