Summary

The open-source identity infrastructure software Zitadel allows administrators to disable the user self-registration. Due to a missing security check in versions prior to 2.64.0, 2.63.5, 2.62.7, 2.61.4, 2.60.4, 2.59.5, and 2.58.7, disabling the "User Registration allowed" option only hid the registration button on the login page. Users could bypass this restriction by directly accessing the registration URL (/ui/login/loginname) and register a user that way. Versions 2.64.0, 2.63.5, 2.62.7, 2.61.4, 2.60.4, 2.59.5, and 2.58.7 contain a patch. No known workarounds are available.

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.

CPEs and fixed versions use Anchore's correction of NVD's data: Added CPE configurations because not yet analyzed by NVD.
