## Description

opentelemetry-go-contrib is a collection of extensions for
OpenTelemetry-Go. The v0.38.0 release of
`go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp` uses the
`httpconv.ServerRequest` function to annotate metric measurements for the
`http.server.request\_content\_length`,
`http.server.response\_content\_length`, and `http.server.duration`
instruments. The `ServerRequest` function sets the `http.target` attribute
value to be the whole request URI (including the query string)[^1]. The
metric instruments do not "forget" previous measurement attributes when
`cumulative` temporality is used, this means the cardinality of the
measurements allocated is directly correlated with the unique URIs handled.
If the query string is constantly random, this will result in a constant
increase in memory allocation that can be used in a denial-of-service
attack. This issue has been addressed in version 0.39.0. Users are advised
to upgrade. There are no known workarounds for this issue.
