EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 6.5 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.3%, top 78% 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, manipulating user-supplied input incorporated into Antlers templates could result in the loss of content and assets, on sites whose templates pass untrusted input into affected areas, and exploitation did not require authentication. This issue is fixed in versions 5.74.1 and 6.24.0.
