CVE-2026-76086Network attack vector

Credential exposure and SSRF via unauthorized settings override

Published Sep 23, 2026 · Updated Sep 23, 2026

SSRF in Verbb Formie before 2.2.23 and 3.0.0 through 3.1.30 allows remote authenticated users to read internal responses via form-settings. IntegrationsController::actionFormSettings applies request-supplied settings without permission checks or an attribute allowlist, so apiUrl can redirect authenticated outbound requests. Low-privileged accounts can receive non-blind responses and expose stored API keys or OAuth tokens.
