High (7.5) in broadcom reactor netty. EPSS 0.9% chance of exploitation in the next 30 days. Fixed in io.projectreactor.netty:reactor-netty-core 1.0.39, 1.1.13.
In Reactor Netty HTTP Server, versions 1.1.x prior to 1.1.13 and versions 1.0.x prior to 1.0.39, it is possible for a user to provide specially crafted HTTP requests that may cause a denial-of-service (DoS) condition.
Specifically, an application is vulnerable if Reactor Netty HTTP Server built-in integration with Micrometer is enabled.
