CVE-2025-11135Public exploitNetwork attack vector

Data compromise and disruption via cookie deserialization

Published Sep 29, 2025 · Updated Sep 29, 2025

Deserialization in PMTicket Project-Management-Software allows remote attackers to affect application data through a crafted cookie. The loadLanguage function in classes/class.database.php deserializes the user_id cookie without validating its serialized contents. No authentication or user interaction is required; published assessments bound the result to limited confidentiality, integrity, and availability effects.
