Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Klever-Go (github.com/klever-io/klever-go), versions up to and including 1.7.16, is vulnerable to a denial of service in its multi-data gossip interceptor. A remote peer that can publish on a topic it serves can send a small compressed payload that expands to gigabytes of memory on the receiving node, potentially crashing it. No fixed version is listed, and the source gives no workaround beyond patching.
