AiAssistant Type Privilege Bypass Vulnerability (CVE-2026-31368)

CVE-2026-31368 is a type privilege bypass vulnerability in AiAssistant, potentially leading to service availability issues and complete compromise of the system.

CVE-2026-31368 describes a type privilege bypass vulnerability affecting AiAssistant. This vulnerability, reported by Honor Device Co., Ltd., can lead to service availability issues. The CVSS v3.1 score is rated as 7.8 (HIGH), indicating a significant risk. A local attacker with low privileges and no user interaction required can exploit this vulnerability, leading to high impact on confidentiality, integrity, and availability. This is a serious concern because it enables low-privileged users to potentially escalate their privileges and disrupt services or gain unauthorized access to sensitive data. Successful exploitation allows for complete system compromise, making this vulnerability a high priority for patching and mitigation.

Attack Chain

  1. Attacker gains initial low-privileged access to the system running AiAssistant.
  2. Attacker leverages CVE-2026-31368 to bypass intended type restrictions within AiAssistant.
  3. The privilege bypass allows the attacker to execute unauthorized code with elevated privileges.
  4. Attacker uses the elevated privileges to access sensitive system resources or data.
  5. Attacker modifies critical system configurations, leading to service disruption.
  6. Attacker installs malicious software, such as a backdoor, for persistent access.
  7. Attacker leverages persistent access to further compromise the system and connected network.

Impact

Successful exploitation of CVE-2026-31368 allows a local attacker to bypass privilege restrictions in AiAssistant. This can lead to a complete compromise of the affected system and potential service disruption. Given the high CVSS score of 7.8, organizations using AiAssistant should consider this a critical vulnerability requiring immediate attention. The confidentiality, integrity, and availability of the system are all at risk.
