EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 6.9 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.6%, top 56% 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).

Grav Form Plugin before 9.1.22 fails to verify page authorization when resolving forms by name across pages, allowing anonymous visitors to execute form actions defined on login-restricted or unpublished pages. Attackers can POST to any public page with a restricted form's name to trigger save, upload, email, or call actions without authentication.
