CVE-2026-97891
Published:November 10, 2026
Updated:November 11, 2026
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.
