API token disclosure via exposed profiling endpoint
Published Nov 30, 2022 · Updated Apr 23, 2025
Information disclosure in Grafana Synthetic Monitoring Agent before 0.12.0 allows remote attackers to read its API token via HTTP. The default HTTP server exposes Go's /debug/pprof/cmdline handler on all interfaces, which returns process arguments containing the token. The endpoint must be reachable on the local network; the stolen token retrieves checks assigned to that agent only when the API accepts a second connection.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
