CVE-2026-86122Network attack vector

Internal service access via unrestricted integration URLs

Published Sep 5, 2026 · Updated Sep 10, 2026

Server-side request forgery in Rowboat 0 through 0.9.1 allows remote authenticated users to query internal services through crafted URLs. validateHttpHttpsUrl accepts any HTTP or HTTPS host, while invokeWebhookTool and invokeMcpTool send requests to the stored destination without excluding private or metadata addresses. Authenticated project access is required; successful requests disclose reachable service responses and permit internal network enumeration.
