MEDIUMPre-NVD 5.55.5—
EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 5.5 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.1%, top 98% 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).

Wings is the server control plane for Pterodactyl, a free, open-source game server management panel. Prior to 1.13.0, unbounded json, yaml, and xml configuration-file parsers in parser.go can process an oversized non-file parser configuration file and exhaust Wings process memory. This issue is fixed in version 1.13.0.
