CVE-2026-44503
CVE-2026-44503 · Kiota abstractions RedirectHandler leaks Cookie/Proxy-Authorization headers on cross-host redirect
This page contains facts from public vulnerability sources. Check the original advisory before updating.
The RedirectHandler middleware in microsoft/kiota-java (com.microsoft.kiota:microsoft-kiota-http-okHttp v1.9.0) and other Kiota libraries fails to strip sensitive HTTP headers when following 3xx redirects to a different host or scheme. Only the Authorization header is removed; Cookie, Proxy-Authorization, and all custom headers are forwarded to the redirect target.
