Vulnerability Overview

The Clearfy Cache – WordPress optimization plugin, Minify HTML, CSS & JS, Defer plugin for WordPress is vulnerable to Sensitive Information Exposure in versions up to 2.4.3. This makes it possible for authenticated attackers, with subscriber-level access and above, to extract sensitive user or configuration data.

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 interaction from a victim user.

CWE-200: Exposure of Sensitive Information to an Unauthorized Actor

Reaching this weakness in Clearfy Cache < 2.4.3 takes an account at Subscriber level or above. Sensitive information exposure means data the application intended to keep internal is returned to a caller who should not be able to see it.

The disclosed data — credentials, tokens, customer records or internal paths — is usually worth more as material for a follow-up attack than as an end in itself. For Clearfy Cache the fix is 2.4.3: builds < 2.4.3 are affected, anything from 2.4.3 onward is not.

Remediation

Update to version 2.4.3, or a newer patched version
