Unauthenticated data disclosure via unrestricted API fetch
Published Apr 6, 2024 · Updated Jul 9, 2026
SSRF in Everywall Ladder 0.0.1 through 0.0.21 allows remote attackers to read network-accessible data through the unauthenticated API. The /api/* handler passes the path-supplied URL to fetchSite, whose HTTP client retrieves it and returns the fetched body and headers without blocking private destinations. Exposure requires network access to an instance without Basic Auth and can disclose data reachable from the Ladder host.
