Summary Qwik City improperly inferred arrays from dotted form field names during FormData parsing. By submitting mixed array-index and object-property keys for the same path, an attacker could cause user-controlled properties to be written onto values that application code expected to be arrays...

Salvo Affected by Denial of Service via Unbounded Memory Allocation in Form Data Parsing

Summary Salvo's form data parsing implementations formdata method and Extractible macro do not enforce payload size limits before reading request bodies into memory. This allows attackers to cause Out-of-Memory OOM conditions by sending extremely large payloads, leading to service crashes and...

undertow: OutOfMemory when parsing form data encoding with application/x-www-form-urlencoded

A flaw was found in Undertow that can cause remote denial of service attacks. When the server uses the FormEncodedDataDefinition.doParseStreamSourceChannel method to parse large form data encoding with application/x-www-form-urlencoded, the method will cause an OutOfMemory issue. This flaw allows...

Unity Linux 20.1050e / 20.1060e / 20.1070e Security Update: pcs (UTSA-2026-006185)

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-006185 advisory. Tornado is a Python web framework and asynchronous networking library. When Tornado's multipart/form- data parser encounters certain errors, it logs a warning but...

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 ...
