github.com/prometheus/prometheus: Prometheus: Denial of Service via uncontrolled memory allocation in remote read endpoint

A flaw was found in Prometheus. An unauthenticated attacker can exploit the remote read endpoint /api/v1/read by sending a specially crafted, small snappy-compressed payload. This payload causes a disproportionately large memory allocation, leading to memory exhaustion and a Denial of Service DoS...

BIT-PROMETHEUS-2026-42154 Prometheus: remote read endpoint allows denial of service via crafted snappy payload

Prometheus is an open-source monitoring system and time series database. Prior to versions 3.5.3 and 3.11.3, the remote read endpoint /api/v1/read does not validate the declared decoded length in a snappy-compressed request body before allocating memory. An unauthenticated attacker can send a sma...
