At a glance
CVE-2022-38454 is a high-severity Cross-Site Request Forgery (CSRF) vulnerability in the Kraken.io Image Optimizer WordPress plugin, affecting versions <= 2.6.5. It carries a CVSS score of 8.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 2.6.6; sites on affected versions should update now. Disclosed September 2022, reported by Rasi Afeef.
Vulnerability Overview
The Kraken.io Image Optimizer plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 2.6.5. This is due to missing nonce validation on the kraken_settings_page() function. This makes it possible for unauthenticated attackers to modify the plugin's settings, via forged request granted they can trick a site administrator into performing an action such as clicking on a link.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.
CWE-352: Cross-Site Request Forgery (CSRF)
Kraken.io Image Optimizer <= 2.6.5 carries this weakness at kraken_settings_page(), and reaching it takes a caller who can reach the endpoint. Cross-site request forgery abuses the fact that browsers attach a victim's cookies to any request, so a state-changing action that only checks who you are, not whether you meant to act, can be triggered from another site.
An attacker who gets a logged-in user to load a crafted page can perform that action as them, with the impact scaling to whatever the victim's role is allowed to do. For Kraken.io Image Optimizer the fix is 2.6.6: builds <= 2.6.5 are affected, anything from 2.6.6 onward is not.
Remediation
Update to version 2.6.6, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to Kraken.io Image Optimizer: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Kraken.io Image Optimizer 2.6.6 closes this, and updating the plugin is the step that ends it.
