Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The flyto-core package before 2.26.7 has a server-side request forgery flaw in its HTTP modules (http.get, http.request, http.batch). The SSRF guard checks only the initial URL, and the requests follow redirects by default without rechecking the target. An attacker who can get a user or workflow to request a URL they control, which redirects to an internal address, can read the internal response body. Upgrade to flyto-core 2.26.7 or later; the source gives no workaround beyond that.
