CVE-2026-49854 Tornado: Out-of-bounds memory access in C extension

Tornado is a Python web framework and asynchronous networking library. Prior to 6.5.6, the optional native extension tornado.speedups implemented websocketmask without validating that the mask argument is exactly four bytes, allowing the C function to read up to three bytes beyond the provided...

CVE-2026-49854

Summary: Tornado’s optional native extension tornado.speedups mishandles the websocket_mask length, reading beyond a four-byte buffer when invoked through the XSRF token decoder with the extension active. This out-of-bounds access affects Tornado up to version 6.5.5 and is fixed in 6.5.6. Impact:...

GHSA-MGF9-4VPG-HJ56 tornado AsyncHTTPClient accumulates decompressed chunks without size limit (gzip bomb)

Tornado's gzip decompression routines work in limited-size chunks, but have no overall limit for the total size of decompressed chunks that they will accumulate There has always been a limit for the total compressed size. This allows a malicious server to consume effectively unlimited amounts of...
