Real-World Exposure

1 pkg affected
🐹github.com/pterodactyl/wings

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Go packages — download data is not available via public APIs for these ecosystems.

Description

Impact

A newly implemented route allowing users to download files from remote endpoints was not properly verifying the destination hostname for user provided URLs. This would allow malicious users to potentially access resources on local networks that would otherwise be inaccessible.

This vulnerability requires valid authentication credentials and is therefore not exploitable by unauthenticated users. If you are running an instance for yourself or other trusted individuals this impact is unlikely to be of major concern to you. However, you should still upgrade for security sake.

Patches

Users should upgrade to the latest version of Wings.

Workarounds

There is no workaround available that does not involve modifying Panel or Wings code.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    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.

  2. Fix

    Update github.com/pterodactyl/wings to 1.2.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-6rg3-8h8x-5xfv is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
