SCA: security update for github.com/klever-io/klever-go (GHSA-w4c6-7r69-w7j9)

high Tenable Cloud Security Plugin ID 442848

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- Klever-Go is the Go implementation of the Klever blockchain protocol. Versions from 1.7.14 through 1.7.17
are vulnerable to a remotely triggerable denial of service. Both REST APIs are started with the Gin
Engine.Run convenience method, which serves requests through Go's default HTTP server with no
ReadHeaderTimeout, ReadTimeout, or MaxHeaderBytes configured. As a result, incoming connections that never
complete their request headers are held open indefinitely. When a REST listener is reachable beyond
localhost through the documented all-interface bind or a Docker port-publish deployment, a single
unauthenticated client can open many slow-header connections and hold them open until server file
descriptors are exhausted, preventing the API from accepting new connections. This renders the REST API
unavailable to legitimate clients. This issue is fixed in version 1.7.18. (CVE-2026-52880)

Solution

Update the github.com/klever-io/klever-go library and its related packages to version 1.7.18 or later.
