EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 4.3 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.3%, top 83% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

Statamic is a Laravel and Git powered content management system (CMS). Prior to 5.74.1 and 6.24.0, an authenticated Control Panel user could use an endpoint intended for the user creation wizard to determine if a given email address belonged to an existing user, without having permission to view users, though the endpoint only exposed user existence and not any other user data. This issue is fixed in versions 5.74.1 and 6.24.0.
