Which packages are affected by CVE-2025-68954?

CVE-2025-68954 affects the following packages: github.com/pterodactyl/wings (Go), pterodactyl/panel (Packagist). Ecosystems affected: Go, Packagist.

How do I fix CVE-2025-68954?

Update github.com/pterodactyl/wings to 1.12.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-68954 is resolved across your whole dependency graph.

How do I detect CVE-2025-68954 in my Go, Packagist dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/pterodactyl/wings, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2025-68954 if there is no patch (or I can't update yet)?

Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.

Is CVE-2025-68954 actively exploited in the wild?

No public exploit code has been indexed for CVE-2025-68954 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

Description

Summary

Pterodactyl does not revoke active SFTP connections when a user is removed from a server instance or has their permissions changes with respect to file access over SFTP. This allows a user that was already connected to SFTP to remain connected and access files even after their permissions are revoked.

Details

When a user opens a connection to a server using the Wings SFTP server instance the permissions are checked and returned from the authentication API call made to the Panel. However, credentials are not checked again after the initial handshake. Thus, if a user is removed from a server in the panel or have their permissions modified, those permissions are not updated in the SFTP connection.

As a result, a user that has already gained access to a server's files via the SFTP subsystem will maintain those permissions until disconnected (via Wings restart, or a manual disconnection on their end).

[!NOTE]

This issue impacts the SFTP subsystem for server files specifically. There is no exposure of Wings private data, or any data outside of a server's local filesystem. Additionally, a user must have been connected to SFTP at the time of their permissions being revoked in order for this issue to be exploited. If a user was not connected, they would not be able to connect once their permissions were reduced.

Fix

Please upgrade to [email protected] and [email protected] to resolve this issue. Patches are available via the implementation PRs, but it is recommended to apply by upgrading the entire instance.
