CVE-2024-23083

Medium severity, CVSS 5.3. EPSS: 0.7% chance of exploitation in the next 30 days.

Time4J Base v5.9.3 was discovered to contain a NullPointerException via the component net.time4j.format.internal.FormatUtils::useDefaultWeekmodel(Locale).

The submission may have been based on a tool that is not sufficiently robust for vulnerability identification.
