Summary

The HttpClient from Reactor Netty, versions 0.9.x prior to 0.9.5, and versions 0.8.x prior to 0.8.16, may be used incorrectly, leading to a credentials leak during a redirect to a different domain. In order for this to happen, the HttpClient must have been explicitly configured to follow redirects.

Risk Assessment

Credential leakage during redirects could allow an attacker to capture authentication data and gain unauthorized access to systems.

Recommendation

Upgrade Reactor Netty to version 0.9.5 or later (for 0.9.x) and to 0.8.16 or later (for 0.8.x). If possible, avoid automatic redirect following or carefully validate destination domains.
