CVE-2026-30230: Flintsh Flare

High severity, CVSS 7.5. EPSS: 0.4% chance of exploitation in the next 30 days.

Flare is a Next.js-based, self-hostable file sharing platform that integrates with screenshot tools. Prior to version 1.7.2, the thumbnail endpoint does not validate the password for password‑protected files. It checks ownership/admin for private files but skips password verification, allowing thumbnail access without the password. This issue has been patched in version 1.7.2.

Affected products

• Flintsh Flare: before 1.7.2 (fixed in 1.7.2)
