CVE-2026-43642
Softaculous Virtualizor before 3.2.9 (Patch 9) and 3.0.0 contains a PHP object injection vulnerability in the billing module handler that allows unauthenticated remote attackers to supply arbitrary serialized PHP objects for deserialization by setting the act parameter to login with the from_billing_module parameter present. Attackers can pass malicious serialized data through the billing_data POST field to the unserialize() function without allowed_classes restrictions, enabling exploitation of available POP chains to achieve remote code execution as root.
