CVE-2025-22227: Vulnerability in VMware Reactor Netty
In some specific scenarios with chained redirects, Reactor Netty HTTP client leaks credentials. In order for this to happen, the HTTP client must have been explicitly configured to follow redirects.
AI Analysis
Technical Summary
The vulnerability CVE-2025-22227 affects VMware Reactor Netty HTTP client versions 1.0.x to 1.3.x. When the HTTP client is configured to follow redirects, specific chained redirect scenarios can cause it to leak credentials. The CVSS 3.1 base score is 6.1, reflecting network attack vector, low attack complexity, no privileges required, user interaction required, scope changed, and low impact on confidentiality and integrity with no impact on availability. There are no known exploits in the wild and no patch or official fix has been provided yet.
Potential Impact
An attacker could potentially obtain leaked credentials during chained HTTP redirects if the client is configured to follow redirects. This leads to a confidentiality breach with limited impact on integrity and no impact on availability. No active exploitation has been reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, avoid configuring the Reactor Netty HTTP client to follow redirects if possible, or carefully control and validate redirect targets to minimize credential exposure risk.
