CVE-2026-65445Network attack vector

Ad suppression via spoofed click-tracking IP

Published Jul 27, 2026 · Updated Jul 27, 2026

Broken access control in Ad Invalid Click Protector 1.3.0 and earlier allows remote attackers to suppress ads for chosen visitor IPs. The click-tracking AJAX endpoint trusts a client-supplied IP address when updating the blocked-IP list instead of deriving the address server-side. No authentication or user interaction is required; forged tracking requests can poison the list with arbitrary victim IPs and prevent ads from being shown to them.
