CVE-2024-8391: Eclipse Vert.x

High severity, CVSS 7.5. EPSS: 0.6% chance of exploitation in the next 30 days.

In Eclipse Vert.x version 4.3.0 to 4.5.9, the gRPC server does not limit the maximum length of message payload (Maven GAV: io.vertx:vertx-grpc-server and io.vertx:vertx-grpc-client).  This is fixed in the 4.5.10 version.  Note this does not affect the Vert.x gRPC server based grpc-java and Netty libraries (Maven GAV: io.vertx:vertx-grpc)

Affected products

• Eclipse Vert.x: from 4.3.0, before 4.5.10 (fixed in 4.5.10)
