CVE-2026-41715 Details
Description
In specific scenarios involving HTTP redirects from a secure to an insecure endpoint, the Reactor Netty HTTP client may leak credentials. In order for this to happen, the HTTP client must have been explicitly configured to follow redirects. Affected versions: Reactor Netty 1.0.0 through 1.0.51; 1.1.0 through 1.1.35; 1.2.0 through 1.2.17; 1.3.0 through 1.3.5.
A vulnerability exists in the Reactor Netty HTTP client, versions 1.0.0 prior to 1.0.51, 1.1.0 prior to 1.1.35, 1.2.0 prior to 1.2.17, and 1.3.0 prior to 1.3.5. In certain scenarios where HTTP redirects occur from a secure to an insecure endpoint, the client may unintentionally expose credentials. This issue arises only if the HTTP client is explicitly set to follow redirects.
Users should upgrade to Reactor Netty version 1.0.52, 1.1.36, 1.2.18, or 1.3.6, depending on their current version. Instructions for upgrading are available on the Spring Enterprise Support site.
