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:\n\n- 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.\n- 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 API, which the cluster processes with the credential configured in Pulsar Manager.\n- The destination of a proxied request can be chosen by the requester, and Pulsar Manager attaches its configured Pulsar admin credential to the request. An unauthenticated user can make Pulsar Manager send this credential to a host of the user's choosing, and the credential can then be used directly against the Pulsar cluster.\n- In versions 0.3.0 and later, Pulsar Manager does not distinguish between privilege levels of its accounts. Every account, including one created through the first issue, effectively has full administrative privileges in Pulsar Manager.\n\nThe impact depends on the version and the deployment. In versions 0.3.0 and later, any user who can reach Pulsar Manager over the network can take full control of Pulsar Manager. In all versions, when Pulsar Manager is configured with an HTTP authentication credential for a Pulsar cluster, any user who can reach Pulsar Manager can perform the Pulsar admin operations that this credential permits and can obtain the credential itself. When Pulsar Manager is configured with the token signing key of a Pulsar cluster, an administrator of Pulsar Manager can create tokens for the cluster.\n\nApache Pulsar Manager is no longer maintained and is completely unsupported. The Apache Pulsar PMC has retired it. There are no supported versions, and no further releases, fixes or security updates will be made for any version. These issues will not be fixed.\n\nUsing Pulsar Manager is not recommended. Users should stop using Pulsar Manager, remove existing deployments, and move to one of the alternatives described in the Administration UI documentation (https://pulsar.apache.org/docs/administration-ui). Users who have exposed Pulsar Manager configured with a Pulsar credential or token signing key should also consider replacing that credential or key.\n\nUntil a deployment is removed, users should not expose Pulsar Manager to untrusted networks, and should restrict network access to it to trusted administrators.","state":0,"publishedAt":"2026-10-21T18:17:37.844+00:00","modifiedAt":"2026-10-23T21:57:46.976+00:00","affected":[{"ecosystem":"Vendor product","name":"Apache Pulsar Manager","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Apache Software Foundation\",\n                    \"product\": \"Apache Pulsar Manager\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0.1.0\",\n                            \"lessThanOrEqual\": \"0.4.0\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","score":10,"severity":"CRITICAL"}],"references":["https://pulsar.apache.org/security/CVE-2026-105944/","https://pulsar.apache.org/docs/administration-ui","https://lists.apache.org/thread.html/hol3z7fzhjntwvrv8xqqwx4l4d2jx796"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-105944","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-105944","identifiers":["CVE-2026-105944"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
