Wings is the server control plane for Pterodactyl, a free, open-source game server management panel. Prior to version 1.12.1, a missing authorization check in multiple controllers allows any user with access to a node secret token to fetch information about any server on a Pterodactyl instance, even if that server is associated with a different node. This issue stems from missing logic to verify that the node requesting server data is the same node that the server is associated with. Any authenticated Wings node can retrieve server installation scripts (potentially containing secret values) and manipulate the installation status of servers belonging to other nodes. Wings nodes may also manipulate the transfer status of servers belonging to other nodes. This vulnerability requires a user to acquire a secret access token for a node. Unless a user gains access to a Wings secret access token they would not be able to access any of these vulnerable endpoints, as every endpoint requires a valid node access token. A single compromised Wings node daemon token (stored in plaintext at /etc/pterodactyl/config.yml) grants access to sensitive configuration data of every server on the panel, rather than only to servers that the node has access to. An attacker can use this information to move laterally through the system, send excessive notifications, destroy server data on other nodes, and otherwise exfiltrate secrets that they should not have access to with only a node token. Additionally, triggering a false transfer success causes the panel to delete the server from the source node, resulting in permanent data loss. Users should upgrade to version 1.12.1 to receive a fix.

EG Risk is EchelonGraph's 0–100 priority score. It fuses impact severity (EG Severity, the CVSS base score, never the KEV-floored or EPSS-lifted EG Score) with real-world exploitation and automatability, under weights EchelonGraph set by hand, so you can rank equal-severity CVEs and fix the most dangerous first.

Mission impact is CISA's Mission & Well-being decision point, and only you can judge it. CISA's table makes it high when Mission Prevalence is Essential — the vulnerable component "directly provides capabilities that constitute at least one MEF for at least one entity" (MEF: mission essential function) — or when Public Well-Being Impact is Irreversible: "multiple fatalities are likely", the cyber-physical system "is likely lost or destroyed", "extreme or serious externalities" are imposed on other parties, or social systems such as elections or the financial grid "are destabilized and potentially collapse".
