tornado: Tornado: Denial of Service via uncontrolled gzip decompression memory consumption

A flaw was found in Tornado, a Python web framework and asynchronous networking library. Its gzip decompression routines process data in limited-size chunks but do not enforce an overall limit on the total accumulated decompressed data. This vulnerability allows a malicious server to consume...

tornado: Tornado: Information disclosure via improper handling of credentials during HTTP redirects

A flaw was found in Tornado's SimpleAsyncHTTPClient. When following a redirect to a different origin, the client improperly retains and forwards sensitive authentication credentials, such as Authorization headers, to the new, potentially untrusted, destination. This vulnerability allows a remote...

OESA-2026-4037 python-tornado security update

Tornado is a Python web framework and asynchronous networking library, originally developed at FriendFeed. By using non-blocking network I/O, Tornado can scale to tens of thousands of open connections, making it ideal for long polling, WebSockets, and other applications that require a long-lived...
