Low risk33th percentile - higher than 33% of all known CVEs
Summary
DeepTutor before version 1.4.10 contains an authorization bypass vulnerability allowing low-privilege users to invoke unrestricted MCP tools. The allowed_mcp_tools function returns None instead of a denied result when mcp_tools is omitted from a user's grant.
Risk Assessment
Attackers or prompt-injected content acting within a user session can enumerate and invoke any configured MCP tool, including filesystem, shell, and browser servers, gaining unauthorized access to sensitive deployment resources.
Recommendation
Upgrade DeepTutor to version 1.4.10 or later immediately, which includes a fix for this vulnerability. As a workaround, restrict access to MCP tools through proper permission configuration.

Improper neutralization of CRLF sequences in IXON VPN Client before version 1.4.7 allows an attacker to execute commands as root or SYSTEM. Configuration values accepted by the local service are written to a file later consumed by a privileged subprocess, without line-ending sequences being neutralized, which allows additional directives to be introduced into that file. The configuration interface accepts changes without authenticating or verifying the origin of the requester. The injected configuration persists on disk across restarts of the client and the operating system, and the VPN connection continues to function normally, so there is no behavioral change visible to the user.

DeepTutor before version 1.4.10 contains an authorization bypass vulnerability that allows low-privilege users to invoke unrestricted MCP tools due to the allowed_mcp_tools function returning None instead of a denied result when mcp_tools is omitted from a user's grant in deeptutor/multi_user/tool_access.py. Attackers or prompt-injected content acting within a user session can enumerate and invoke any configured MCP tool, including filesystem, shell, and browser servers, gaining unauthorized access to sensitive deployment resources.
