    CVE-2024-28867

    Published: 29 Mar 2024Last Modified: 12 Aug 2026

    Summary: Swift Prometheus un-sanitized metric name or labels can be used to take over exported metrics

    Details: Swift Prometheus is a Swift client for the Prometheus monitoring system, supporting counters, gauges and histograms. In code which applies _un-sanitized string values into metric names or labels_, an attacker could make use of this and send a `?lang` query parameter containing newlines, `}` or similar characters which can lead to the attacker taking over the exported format -- including creating unbounded numbers of stored metrics, inflating server memory usage, or causing "bogus" metrics. This vulnerability is fixed in2.0.0-alpha.2.
