4DescriptionCVE.org
The CMP WordPress plugin before 4.1.18 does not sanitise and escape a settings value before outputting it on the coming-soon page, allowing users with the Editor role (when the administrator has granted the Editor role access to the CMP WordPress plugin before 4.1.18's admin-bar controls) to inject arbitrary web scripts that execute when a visitor views the page.

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Two conditions must both be satisfied: first, the WordPress site must be running CMP plugin version 4.1.17 or earlier; second, an administrator must have explicitly granted the Editor role access to CMP admin-bar controls - this is a non-default configuration that requires deliberate action by a site administrator. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Real-world risk is low across every available signal. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
