Upgrade flyto-core to version 2.26.7 or higher.
Overview
flyto-core is an A workflow engine with 412 built-in modules. Trace every step. Replay from any point.
Affected versions of this package are vulnerable to Server-side Request Forgery (SSRF) via the core.api.http_get, core.api.http_post, graphql.query, graphql.mutation, monitor.http_check, communication.slack_send, notification.discord.send_message, notification.slack.send_message, notification.teams.send_message, ai.vision_analyze, verify.visual_diff, browser.proxy_rotate, and the agent/llm inline base_url branch modules, which perform outbound requests to client-controlled URLs without proper validation. An attacker can access sensitive internal resources and potentially obtain cloud metadata credentials or interact with internal APIs by supplying crafted URLs to these modules.
