Wings is the server control plane for Pterodactyl Panel. A vulnerability affecting versions prior to 1.7.5 and versions 1.11.0 prior to 1.11.6 impacts anyone running the affected versions of Wings. This vulnerability can be used to gain access to the host system running Wings if a user is able to modify an server's install script or the install script executes code supplied by the user (either through environment variables, or commands that execute commands based off of user data). This vulnerability has been resolved in version v1.11.6 of Wings, and has been back-ported to the 1.7 release series in v1.7.5. Anyone running v1.11.x should upgrade to v1.11.6 and anyone running v1.7.x should upgrade to v1.7.5.
There are no workarounds aside from upgrading. Running Wings with a rootless container runtime may mitigate the severity of any attacks, however the majority of users are using container runtimes that run as root as per the Wings documentation. SELinux may prevent attackers from performing certain operations against the host system, however privileged containers have a lot of freedom even on systems with SELinux enabled.
It should be noted that this was a known attack vector, for attackers to easily exploit this attack it would require compromising an administrator account on a Panel. However, certain eggs (the data structure that holds the install scripts that get passed to Wings) have an issue where they are unknowingly executing shell commands with escalated privileges provided by untrusted user data.
What the EG score is made of (scorer v4.0: the three questions the 0–10 score mixes, published apart · methodology)
The EG score (9.0): severity, escalated by confirmed exploitation. This CVE's 9.0 is its impact severity (EG Severity), not escalated.

A fix is available. Apply it within your standard update timelines.
Exploitation none (CISA Vulnrichment) · Automatable no (CISA Vulnrichment) · Technical impact total (CISA Vulnrichment). All three are CISA's SSVC values (Vulnrichment). EchelonGraph applied CISA's decision table to them; CISA publishes SSVC inputs and the table, not a decision for each CVE. 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".
