CVE-2026-67424

Description

Flyto2 Core is an execution kernel for automation and AI-agent workflows. Prior to 2.26.7, the HTTP modules http.get, http.request, and http.batch in src/core/modules/atomic/http/get.py, src/core/modules/atomic/http/request.py, and src/core/modules/atomic/http/batch.py validate only the initial URL, then follow redirects with allow_redirects=True and without per-hop Location revalidation, allowing a public URL to redirect into internal address space and return the internal response body. This issue is fixed in version 2.26.7.
