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.\n\n## Affected\n\n- `SuggestArr >= 1.0.4 < 3.0.0`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"abyssal","depthScore":63,"depthScoreParts":{"impact":51.2,"likelihood":0,"exploitation":12,"ransomware":0},"changes":[{"seq":226007,"id":"CVE-2026-113703","ts":1792516430103,"field":"exploit_available","old":"false","new":"true"}]}
