CVE-2024-28867 is a high-severity vulnerability rated 7.4/10 on the CVSS scale. 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. EPSS estimates a 0.65% chance of exploitation in the next 30 days.
