Summary
docling-serve versions 1.14.0 through 1.36.0 contain a missing authentication flaw (CWE-306) in its memory management endpoints. An unauthenticated remote attacker can reach these endpoints without the configured API key and read process and cgroup memory telemetry and object type histograms. The attacker can also force repeated heap enumeration.

Description from the CNA
docling-serve 1.14.0 through 1.36.0 contains a missing authentication vulnerability that allows unauthenticated attackers to access /v1/memory/stats and /v1/memory/counts because they omit the require_auth dependency. Attackers can bypass the configured DOCLING_SERVE_API_KEY to read process and cgroup memory telemetry, object type histograms, and force repeated gc.collect() heap enumeration.
