CVE-2026-74908: Getgrav Grav

Medium severity, CVSS 4.6. EPSS: 0.3% chance of exploitation in the next 30 days.

Grav plugin-api before 1.0.15 contains a script injection vulnerability where the SVG sanitizer only checks for the exact extension 'svg', allowing .svgz and .xhtml files to bypass sanitization and be stored unsanitized. Attackers with api.media.write permission can upload files containing executable script payloads that execute in the site origin when accessed by administrators or visitors.
