Last modified Jun 17, 2026

CVE-2024-8391 is a medium-severity vulnerability rated 6.9/10 on the CVSS scale. 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). EPSS estimates a 0.58% chance of exploitation in the next 30 days.
