CVE-2026-103068: CWE-266 Incorrect Privilege Assignment in ByteCore Stack ByteCoreStack – MCP Connector for AI Tools
Subscriber Privilege Escalation in ByteCoreStack – MCP Connector for AI Tools <= 1.2.2 versions.
AI Analysis
Technical Summary
This vulnerability, identified as CWE-266 (Incorrect Privilege Assignment), affects ByteCoreStack – MCP Connector for AI Tools versions <= 1.2.2. It allows a user with limited privileges (subscriber) to escalate their privileges improperly, potentially gaining unauthorized access or control. The CVSS 3.1 vector indicates network attack vector, low attack complexity, privileges required are low, no user interaction needed, and the impact is high on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation could lead to full compromise of the affected system's confidentiality, integrity, and availability due to privilege escalation. This means an attacker with subscriber-level access could gain higher privileges, potentially leading to unauthorized data access, modification, or disruption of service.
Mitigation Recommendations
No patch or official fix information is provided in the available data. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict subscriber privileges and monitor for suspicious activity related to privilege escalation attempts.
