In Dradis Community Edition, the ProvidersController and AgentsController gate their admin_required before_action on `defined?(Dradis::Pro)`, a constant that is never defined in CE, so the authorization check is never applied. As a result, any authenticated (non-admin) user can create an AI provider pointing to an arbitrary HTTP/HTTPS address (including internal/link-local hosts such as http://169.254.169.254) and reassign the built-in Roslin agent to use it. When an AI interaction is triggered, the server issues a request to the attacker-supplied URL (server-side request forgery). For non-2xx responses, the target's response body is reflected verbatim to the attacker's browser via ActionCable/Turbo Stream error messages, making the SSRF readable.

CVE-2026-79788 affects Dradis Community Edition versions 5.1.0 through 5.2.0. The ProvidersController and AgentsController incorrectly gate their admin_required authorization check on the constant Dradis::Pro, which is never defined in the CE edition, meaning the check is never enforced. Any authenticated non-admin user can exploit this to create an AI provider pointing to an arbitrary HTTP/HTTPS address, including internal or link-local hosts like http://169.254.169.254. When an AI interaction is triggered, the server makes a request to the attacker-controlled URL, constituting a Server-Side Request Forgery (SSRF). For non-2xx HTTP responses, the target's response body is reflected back to the attacker via ActionCable/Turbo Stream error messages, making the SSRF readable and exploitable for internal network reconnaissance. The vulnerability stems from a broken authorization logic flaw combined with insufficient URL validation.
