CVE-2026-97891

Quick assessment

Affected

Eclipse Foundation Eclipse Kura

Exploitation

No confirmed in-the-wild exploitation; assess based on exposure

Recommended action

Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 Eclipse Kura 5.0.0 至 5.6.2 版本中，Web 控制台会在检查 HTTP 方法、解析请求或验证任何提交的凭据之前，为其内置的身份验证端点（/admin/auth、/admin/login/password、/admin/login/cert）的每个请求分配一个新的 HTTP 会话，且未对可分配的此类会话数量进行限制。未认证的客户端若向这些端点发送请求，同时不遵守返回的会话 Cookie，将导致服务器分配无上限数量的会话，从而耗尽 JVM 堆内存并造成 Kura 进程崩溃。

Vulnerability Title

N/A

Source: CVE Program / CVE List V5

Vulnerability Description

In Eclipse Kura version 5.0.0 to 5.6.2, the Web Console allocates a new HTTP session for every request to its built-in authentication endpoints (/admin/auth, /admin/login/password, /admin/login/cert) before checking the HTTP method, parsing the request, or validating any submitted credentials, and does not limit how many such sessions can be allocated. An unauthenticated client that sends requests to these endpoints without honoring the returned session cookie can cause the server to allocate an unbounded number of sessions, exhausting the JVM heap and crashing the Kura process.
