The French national cybersecurity agency ANSSI has published an advisory detailing multiple vulnerabilities in Spring Cloud Gateway and Spring Cloud Sleuth products. The flaws, tracked as CVE-2026-41708 and CVE-2026-47825, allow attackers to trigger remote denial of service conditions. The vendor has also identified an unspecified security issue whose details have not been disclosed.
Affected versions span a wide range of Spring Cloud Gateway releases, from 3.1.x through 5.0.x, as well as Spring Cloud Sleuth 3.1.x series. Organizations running these components should prioritize patching, as the remote exploitability of the denial of service condition presents a clear operational risk.
VMware has released patches addressing these issues. Administrators should upgrade to the fixed versions specified in the vendor security bulletins: Cloud Gateway 3.1.13+, 4.2.9+, 4.3.4.1/4.3.5+, or 5.0.1.1/5.0.2+, and Cloud Sleuth 3.1.14+.

What this brief leaves out
This page is the free tier: the write-up, the severity, the names. In the app the same report carries live profiles of the CVEs it names. The paid plans add the security research and news reporting the free tier leaves out.
It sits in a corpus of 16,436 reports from 149 sources, 661 of them written in the last seven days, and it grows through the day.
A new account starts with three days of all of it, no card, then keeps the government and CERT reporting free. Slack alerts are a paid-plan feature: name the vendors you run and Slack hears about the reports that touch them, not the rest of the week's. Nothing is charged unless you subscribe.
