CVE-2026-86100: OWEN2345 Camaleoncms

Medium severity, CVSS 6.4. EPSS: 0.3% chance of exploitation in the next 30 days.

Camaleon CMS versions 2.7.5 through 2.9.1 fail to validate redirect targets when fetching remote files in the Upload from URL media feature. Authenticated attackers can supply URLs that pass initial validation but redirect to internal network addresses, allowing server-side request forgery to internal services.

Affected products

• OWEN2345 Camaleoncms: from 2.7.5, before 2.9.2 (fixed in 2.9.2)
