CVE-2026-40877Network attack vectorHinoki check available

Remote code execution via preference object injection

Published Aug 24, 2026 · Updated Aug 24, 2026

PHP object injection in Combodo iTop before 3.2.3 allows remote authenticated users to execute code through user preferences. The advisory identifies the user preference functionality as the injection point but does not disclose the deserialization call or attacker-controlled field. Exploitation requires low privileges and user interaction and executes unexpected code on the server, with confidentiality and integrity impact but no reported service interruption.
