CVE-2026-119039
validatedZero produced an exploit or a check.GHSA-hx9j-f48g-rh4h ↗EUVD-2026-124275 ↗
description
Defender Security versions earlier than 6.4.1 may accept a requester-controlled IP address when applying firewall and lockout rules. An unauthenticated attacker may bypass IP-based restrictions, appear to use an allowlisted address, or cause misleading activity records when those controls rely on the derived address.
mitigation
Update Defender Security to version 6.4.1 or later. Until the update is deployed, do not rely solely on the plugin's IP-based allowlisting, blocking, or lockout decisions.
fixed in 6.4.1
outcome
Check only, differential: the check fires on the vulnerable build and is silent on the patched one.
