Machine-written summary

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

The Go package github.com/getarcaneapp/arcane/backend/v2, versions before 2.11.0, is affected. A caller holding a valid environment access token, sent in the X-Arcane-Agent-Token header, can reach admin-only routes such as the /api/debug/pprof diagnostic endpoints, which expose runtime profiling data that should be limited to global administrators. Upgrade to version 2.11.0 or later. The source gives no workaround.
