EchelonGraph scoreMEDIUM confidence

This critical-severity CVE scores 9.9 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.5% (41st percentile of EPSS-scored CVEs). 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 1.12.3, {{config.}} placeholders in egg configuration-file templates allow a low-privileged user to read {{config.token}}, {{config.token_id}}, and {{config.docker.registries}} from the full daemon configuration. This issue is fixed in version 1.12.3.

Exploitation none (CISA Vulnrichment) · Automatable no (CISA Vulnrichment) · Technical impact total (CISA Vulnrichment). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
