CVE-2026-86100 PUBLISHED

Camaleon CMS 2.7.5 through 2.9.1 SSRF via HTTP Redirect in Upload from URL

Assigner: VulnCheck
Reserved: 04.09.2026 Published: 04.09.2026 Updated: 04.09.2026

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.
