CVE-2026-103292: Tryghost Ghost

High severity, CVSS 8.0. EPSS: 0.2% chance of exploitation in the next 30 days.

Ghost versions from 0.5.3 through versions prior to 6.50.0 fail to sanitize the data placed in the JSON-LD HTML tag emitted by the {{ghost_head}} helper. An authenticated user with limited privileges can inject unescaped content that is rendered as script in the published page, potentially leading to compromise of a staff user's admin session when that user views the affected page.

Affected products

• Tryghost Ghost: from 0.5.3, before 6.50.0 (fixed in 6.50.0)
