CVE-2026-108147

Description

A flaw was found in Django. A remote attacker could cause a Denial of Service (DoS) by submitting a specially crafted multipart request with base64-encoded file data. When handling these uploads, the parser buffers the data entirely into system memory regardless of configured upload memory limits, which can exhaust server memory and disrupt application availability.

Statement

This vulnerability is rated as having a Low severity because typical Red Hat environments deploy web services behind reverse proxies and ingress controllers that enforce global request payload size constraints, substantially limiting the memory consumption blast radius. Furthermore, exploitation requires targeting specific application endpoints that accept multipart file submissions with obsolete base64 transfer encoding schemes. While excessive memory allocation may impact individual application worker processes, the flaw cannot be leveraged to achieve code execution or compromise data confidentiality or integrity.

Mitigation

Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.

Common Vulnerability Scoring System (CVSS) Score Details

Info alert:Important note

CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

The following CVSS metrics and score provided are preliminary and subject to review.

Understanding the Weakness (CWE)

Availability

Technical Impact: DoS: Resource Consumption (CPU); DoS: Resource Consumption (Memory); DoS: Resource Consumption (Other)

When allocating resources without limits, an attacker could prevent other systems, applications, or processes from accessing the same type of resource. It can be easy for an attacker to consume many resources by rapidly making many requests or causing larger resources to be used than is needed.
