CVE-2025-67995 is a vulnerability identified in LoftOcean's PatioTime product, specifically versions before 2.1. The issue arises from insecure deserialization of untrusted data, which allows an attacker to inject malicious objects during the deserialization process. Deserialization vulnerabilities occur when applications deserialize data without sufficient validation, enabling attackers to craft malicious payloads that can execute arbitrary code, manipulate application logic, or cause denial of service. In this case, the vulnerability is categorized as object injection, a serious form of deserialization flaw that can lead to remote code execution or privilege escalation. The vulnerability was reserved in December 2025 and published in February 2026, but no CVSS score has been assigned yet, and no known exploits have been reported in the wild. The affected product, PatioTime, is likely used in smart home or IoT contexts given the vendor's profile, which increases the risk of widespread impact if exploited. The lack of patches or mitigations currently available means organizations must rely on defensive coding practices and network-level protections until a fix is released.

If exploited, this vulnerability could allow attackers to execute arbitrary code remotely, leading to full compromise of affected systems running PatioTime. This threatens confidentiality by exposing sensitive user data, integrity by allowing unauthorized modification of system behavior or data, and availability by potentially causing system crashes or denial of service. Given PatioTime's probable deployment in smart home or IoT environments, exploitation could also lead to physical security risks or disruption of critical home automation functions. The ease of exploitation is high since deserialization flaws often do not require authentication or user interaction if the attacker can supply crafted data to the vulnerable component. The scope includes all PatioTime versions prior to 2.1, potentially affecting a broad user base globally. The absence of known exploits in the wild currently limits immediate risk but does not reduce the potential severity once exploit code becomes available.

Organizations should immediately audit their use of PatioTime and identify any components that deserialize data from untrusted sources. Until patches are available, apply strict input validation and sanitization on all serialized data inputs. Employ application-layer firewalls or intrusion detection systems to monitor and block suspicious deserialization payloads. Restrict network access to PatioTime services to trusted sources only. Implement runtime application self-protection (RASP) or sandboxing techniques to limit the impact of potential exploitation. Engage with LoftOcean for timely updates and patches, and plan for rapid deployment once fixes are released. Additionally, conduct security training for developers on secure deserialization practices and consider adopting safer serialization formats that do not allow arbitrary object instantiation.
