GHSA-387m-935m-c4vw: Micronaut doesn't set a maximum redirect count for its HTTP Client, enabling infinite loop DoS

0
High
Published: 07/09/2026 (07/09/2026, 13:36:49 UTC)
Source: GCVE Database
Product: io.micronaut:micronaut-http-client

Description

The Micronaut HTTP Client, which is based on Netty, does not limit the number of HTTP redirects it will follow. This lack of a maximum redirect count can cause an infinite redirect loop, potentially leading to a denial-of-service (DoS) condition. Versions prior to 3.10.7 are affected. Patches are available in Micronaut versions 3.10.7 and later, 4.10.24 and later, and 5.0.1 and later.

Technical Analysis

The vulnerability in the Netty-based Micronaut HTTP Client arises because it does not impose a maximum redirect count. This allows an attacker to craft HTTP responses that cause the client to follow redirects indefinitely, resulting in a denial-of-service attack by exhausting resources. The issue affects versions of Micronaut HTTP Client before 3.10.7. Official patches have been released for Micronaut 3 (>=3.10.7), Micronaut 4 (>=4.10.24), and Micronaut 5 (>=5.0.1) to address this problem.

Potential Impact

An attacker can exploit this vulnerability by causing the Micronaut HTTP Client to enter an infinite redirect loop, which leads to denial-of-service by consuming excessive client resources. There is no impact on confidentiality or integrity, only availability is affected.

Mitigation Recommendations

Official patches are available and should be applied. Upgrade to Micronaut HTTP Client version 3.10.7 or later, 4.10.24 or later, or 5.0.1 or later. No workarounds are available.
