python-tornado: Tornado is a Python web framework and asynchronous networking library
CVE-2026-49853 is fixed in 10 products on 1 platform, first by OPENSUSE-SU-2026:21067-1, released June 26, 2026. It is not reported as exploited. Patch Radar priority: High.
Tornado is a Python web framework and asynchronous networking library. Prior to 6.5.6, SimpleAsyncHTTPClient shallow-copied redirected requests and removed only the Host header, leaving Authorization, auth_username, auth_password, and auth_mode in place when a redirect changed scheme, host, or port. This issue is fixed in version 6.5.6.
