PYSEC-2026-1613 Synapse allows unsupported content types to lead to memory exhaustion

Impact In Synapse before 1.120.1, multipart/form-data requests can in certain configurations transiently increase memory consumption beyond expected levels while processing the request, which can be used to amplify denial of service attacks. Patches Synapse 1.120.1 resolves the issue by denying...

PYSEC-2026-1851 Denial of service (DoS) via deformation `multipart/form-data` boundary

Summary When parsing form data, python-multipart skips line breaks CR \r or LF \n in front of the first boundary and any tailing bytes after the last boundary. This happens one byte at a time and emits a log event each time, which may cause excessive logging for certain inputs. An attacker could...

PYSEC-2026-1944 Litestar allows unbounded resource consumption (DoS vulnerability)

Summary Litestar offers multiple methods to return a parsed representation of the request body, as well as extractors that rely on those parsers to map request content to structured data types. Multiple of those parsers do not have size limits when reading the request body into memory, which allo...

PYSEC-2026-1943 Starlette Denial of service (DoS) via multipart/form-data

Summary Starlette treats multipart/form-data parts without a filename as text form fields and buffers those in byte strings with no size limit. This allows an attacker to upload arbitrary large form fields and cause Starlette to both slow down significantly due to excessive memory allocations and...

PYSEC-2026-1098 aiohttp vulnerable to Denial of Service when trying to parse malformed POST requests

Summary An attacker can send a specially crafted POST multipart/form-data request. When the aiohttp server processes it, the server will enter an infinite loop and be unable to process any further requests. Impact An attacker can stop the application from serving requests after sending a single...

PYSEC-2026-1850 python-multipart vulnerable to Content-Type Header ReDoS

Summary When using form data, python-multipart uses a Regular Expression to parse the HTTP Content-Type header, including options. An attacker could send a custom-made Content-Type option that is very difficult for the RegEx to process, consuming CPU resources and stalling indefinitely minutes or...

CVE-2026-54283

A flaw was found in Starlette where the request.form method silently ignores configured resource limits maxfields and maxpartsize when parsing application/x-www-form-urlencoded data. An unauthenticated attacker can exploit this by sending a urlencoded request body with an arbitrarily large number...
