io.quarkus/quarkus-rest: io.quarkus/quarkus-vertx-http: io.quarkus.resteasy.reactive/resteasy-reactive: Quarkus REST - Unbounded multipart MIME part-header accumulation allows remote OOM denial of service

A flaw was found in Quarkus REST. An unauthenticated remote attacker can exploit this vulnerability by sending a crafted multipart/form-data request with an excessively large header section. This unbounded accumulation of MIME part-header bytes can exhaust the Java Virtual Machine JVM heap memory...

CVE-2026-59921 Netty: CRLF Injection via Multipart Filename in Netty HttpPostRequestEncoder

Netty is an asynchronous, event-driven network application framework. Prior to versions 4.1.136.Final and 4.2.16.Final, HttpPostRequestEncoder constructs multipart HTTP request bodies by directly concatenating user-supplied filenames and field names into Content-Disposition MIME headers without...

CVE-2026-59921

CVE-2026-59921 affects Netty’s HttpPostRequestEncoder. Before 4.1.136.Final and 4.2.16.Final, multipart HTTP request bodies were built by directly concatenating user-supplied filenames/field names into Content-Disposition headers without validating CRLF. This allows an attacker-controlled filenam...

Python Library aiohttp < 3.14.0 Header Injection

The version of the aiohttp Python library installed on the remote host is prior to 3.14.0. It is, therefore, affected by a vulnerability: - Prior to 3.14.0, attacker-controlled input included into multipart/payload headers can be used to modify a request to inject additional headers or similar. I...

EUVD-2026-39629

An unauthenticated NULL pointer dereference vulnerability exists in IEEE8021xupload.cgi in GeoVision GV-LPC2011 and GV-LPC2211 V1.12 and earlier. The vulnerability is caused by improper validation of multipart upload headers when processing certificate-related upload fields. A remote attacker may...
