CVE-2026-31958 (GCVE-0-2026-31958)

Vulnerability from cvelistv5 – Published: 2026-03-11 19:27 – Updated: 2026-04-01 14:32

Title

Tornado has a DoS due to too many multipart parts

Summary

Tornado is a Python web framework and asynchronous networking library. In versions of Tornado prior to 6.5.5, the only limit on the number of parts in multipart/form-data is the max_body_size setting (default 100MB). Since parsing occurs synchronously on the main thread, this creates the possibility of denial-of-service due to the cost of parsing very large multipart bodies with many parts. This vulnerability is fixed in 6.5.5.

Severity ?

8.7 (High)
