Lifecycle Timeline
4DescriptionCVE.org
The Clearfy Cache WordPress plugin before 2.4.3 does not perform a capability check in one of its admin-page dispatch paths, allowing any authenticated user such as a Subscriber to render admin-only settings pages and disclose their contents, including administrative nonces, while the canonical page URL correctly restricts access.
AnalysisAI
Clearfy Cache WordPress plugin versions before 2.4.3 exposes admin-only settings pages and their contents - including administrative nonces - to any authenticated user at Subscriber level or above due to a missing capability check on an alternate admin-page dispatch path. While the canonical admin URL enforces access controls correctly, the unguarded dispatch path bypasses those restrictions entirely. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid WordPress user account at Subscriber level or above - unauthenticated users cannot trigger the vulnerable path, consistent with CVSS PR:L. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | CVSS 4.3 (Medium) with vector AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N accurately reflects the bounded severity: network-reachable, low complexity, but requires authentication at subscriber level and yields only limited confidentiality impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker registers or uses an existing Subscriber-level WordPress account on a target site running Clearfy Cache below 2.4.3. Using the publicly available WPScan proof-of-concept, they send a crafted authenticated HTTP request to the unguarded admin dispatch path, bypassing capability checks to render the Clearfy Cache settings admin page and extract one or more administrative nonces. … |
| Remediation | Upgrade Clearfy Cache to version 2.4.3 or later, which is the vendor-released patch per WPScan and EUVD-2026-52597 advisory data. … Detailed patch versions, workarounds, and compensating controls in full report. |
