CVE-2026-113703

9.1 critical SSVC exploitation: poc Deferred

SuggestArr before 3.0.0 contains an authentication bypass vulnerability in its local_bypass authentication mode where enforce_authentication() in api_service/auth/middleware.py trusts the client-controlled request.remote_addr value, which is derived from the spoofable X-Forwarded-For header due to ProxyFix(x_for=1) configuration in api_service/app.py. Attackers can send a request with X-Forwarded-For set to a trusted CIDR address such as 127.0.0.1 to be granted an unauthenticated admin session via _load_bypass_user_context(), gaining full administrative access to endpoints like /api/users and /api/jobs without providing any credentials.

Fix

Nothing published yet: no patch, vendor advisory or mitigation reference on NVD, no vendor advisory in the News for this CVE, not in CISA's KEV, no fixed package version. BaselineWatch does not guess at one.
