Overview
CVE-2026-105944 is a known-severity vulnerability. It was published on October 21, 2026.
Technical description
Apache Pulsar Manager is a web console for administering Apache Pulsar clusters. It has its own user accounts and login, and it can be configured with an HTTP authentication credential, such as a token, that it uses to call the Pulsar admin API on behalf of its users. Pulsar Manager has the following security issues:
- The operation for creating the initial administrator (superuser) account is available without authentication, and it remains available after the instance has been initialized. Anyone who can reach Pulsar Manager can create an additional administrator account at any time and log in with it. This issue affects versions 0.3.0 and later.
- Requests to the Pulsar admin API that Pulsar Manager proxies to the configured Pulsar cluster are not subject to Pulsar Manager's authentication. Version 0.2.0 checks the caller's permissions for some of these requests, but not for all of them. An unauthenticated user can therefore use Pulsar Manager to send requests to the Pulsar admin A
