CVE-2015-20116: Improper Neutralization of Input During Web Page Generation

Next Click Ventures RealtyScript 4.0.2 fails to properly sanitize CSV file uploads, allowing attackers to inject malicious scripts through filename parameters in multipart form data. Attackers can upload files with XSS payloads in the filename field to execute arbitrary JavaScript in users'...

Denial Of Service (DoS)

Tornado is vulnerable to Denial of Service DoS. The vulnerability is due to synchronous parsing of multipart/form-data without limiting the number of parts, allowing attackers to send large requests with many parts that consume excessive CPU and block the main thread...

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...
