CVE-2026-67435 · linuxfabrik-lib: fetch() forwards credential headers across a cross-origin redirect

This page contains facts from public vulnerability sources. Check the original advisory before updating.

linuxfabrik-lib provides Python modules for database access, caching, shell execution, and API integrations. Prior to version 6.0.0, lib.url.fetch() followed cross-origin redirects while forwarding caller-supplied credential headers other than Authorization and Cookie, allowing a malicious redirect-capable server to receive headers such as X-Auth-Token from authenticated monitoring requests. This issue is fixed in version 6.0.0.
