CVE-2026-82397 is a denial of service vulnerability in Tornado web framework versions prior to 6.5.8. It arises because Tornado parses application/x-www-form-urlencoded request bodies using urllib.parse.parse_qs without limiting the maximum number of fields. An attacker can send a large request body composed mostly of separators, causing the parser to generate tens of millions of fields synchronously on the event loop, stalling the entire server process. This vulnerability requires no authentication and affects any route accepting form posts. Join the discussion | CVE Database V5 | 09/03/2026, 10:11:36 UTC Added: 08/31/2026, 21:37:41 UTC |
