Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 35.4th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
This vulnerability is AI-related — categorised as AI Agent Protocols and Integrations; in the Protocol-Specific Risks risk domain.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).
Deeper analysis
CVE-2026-7319 is a path traversal vulnerability (CWE-22) affecting elinsky execution-system-mcp version 0.1.0. The flaw exists in the _get_context_file_path function located in the file src/execution_system_mcp/server.py within the add_action Tool component. Manipulation of the 'context' argument triggers the path traversal issue.
The vulnerability carries a CVSS v3.1 base score of 7.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L), rated as high severity. Remote attackers can exploit it without privileges or user interaction, requiring only low attack complexity over the network. Successful exploitation enables limited impacts on confidentiality, integrity, and availability through path traversal.

Requires validation of the 'context' argument in _get_context_file_path to block path traversal sequences like '../', directly preventing remote exploitation.
Mandates timely identification, reporting, and correction of the path traversal flaw in elinsky execution-system-mcp 0.1.0 server.py.
Enforces restrictions on inputs to the 'context' argument, prohibiting traversal characters and limiting manipulation in the add_action Tool component.
