Credential disclosure via cross-origin redirect header forwarding
Published Jul 29, 2026 · Updated Jul 29, 2026
SSRF in Linuxfabrik Monitoring Plugins before 6.0.0 allows remote authenticated users to disclose credential headers through redirects. lib.url.fetch() follows cross-origin redirects and forwards caller-supplied headers other than Authorization and Cookie to the redirect target. Exploitation requires a monitored endpoint that can issue a crafted redirect; exposed headers such as X-Auth-Token can authorize access to the target API.
