### Vulnerable Library - github.com/Prometheus/client_golang-v1.10.0

Prometheus instrumentation library for Go applications

Library home page: https://proxy.golang.org/github.com/prometheus/client_golang/@v/v1.10.0.zip

Dependency Hierarchy: - :x: **github.com/Prometheus/client_golang-v1.10.0** (Vulnerable Library)

Found in base branch: master

### Vulnerability Details

client_golang is the instrumentation library for Go applications in Prometheus, and the promhttp package in client_golang provides tooling around HTTP servers and clients. In client_golang prior to version 1.11.1, HTTP server is susceptible to a Denial of Service through unbounded cardinality, and potential memory exhaustion, when handling requests with non-standard HTTP methods. In order to be affected, an instrumented software must use any of `promhttp.InstrumentHandler*` middleware except `RequestsInFlight`; not filter any specific methods (e.g GET) before middleware; pass metric with `method` label name to our middleware; and not have any firewall/LB/proxy that filters away requests with unknown `method`. client_golang version 1.11.1 contains a patch for this issue. Several workarounds are available, including removing the `method` label name from counter/gauge used in the InstrumentHandler; turning off affected promhttp handlers; adding custom middleware before promhttp handler that will sanitize the request method given by Go http.Request; and using a reverse proxy or web application firewall, configured to only allow a limited set of methods.
