EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 7.5 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.7%, top 49% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

Dragonfly is an in-memory data store built for modern application workloads. Prior to 1.39.0, a crafted RESTORE payload triggers an out-of-bounds read in DragonflyDB's listpack collection loaders, crashing the entire server process (SIGSEGV). Because DragonflyDB requires no authentication by default and RESTORE is a normal keyspace command, an unauthenticated remote attacker can crash the server with a single ~24-byte command — a remote, repeatable denial of service. This vulnerability is fixed in 1.39.0.
