CVE-2026-108749 PUBLISHED

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.
