High severity, CVSS 8.2. EPSS: 0.6% chance of exploitation in the next 30 days.

As a result, an unauthenticated attacker can inject arbitrary SQL through a URL parameter on pages using the "Date Menu of news articles" plugin. Exploitation requires the "Date Menu of news articles" plugin to be in use and the TypoScript/Plugin setting disableOverrideDemand not to be enabled.
