multipart vulnerable to ReDoS in `parse_options_header()`

Summary The parseoptionsheader function in multipart.py uses a regular expression with an ambiguous alternation, which can cause exponential backtracking ReDoS when parsing maliciously crafted HTTP or multipart segment headers. This can be abused for denial of service DoS attacks against web...

SUSE CVE-2026-31958

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 maxbodysize setting default 100MB. Since parsing occurs synchronously on the main thread, this creates the possibility ...

CVE-2026-31958

Tornado (Python) before 6.5.5 is vulnerable in its multipart/form-data parsing: the only limit is max_body_size (default 100MB) and parsing occurs synchronously on the main thread, enabling denial-of-service via very large multipart bodies with many parts. The issue is fixed in 6.5.5. CVSS metric...
