CVE-2025-69255 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. RustFS is a distributed object storage system built in Rust. In versions 1.0.0-alpha.13 to 1.0.0-alpha.77, a malformed gRPC GetMetrics request causes get_metrics to unwrap() failed deserialization of metric_type/opts, panicking the handler thread and enabling remote denial of service of the metrics endpoint. EPSS estimates a 0.28% chance of exploitation in the next 30 days.
