The vulnerability resides in the \u003ccode\u003e_get_context_file_path\u003c/code\u003e function located within the \u003ccode\u003esrc/execution_system_mcp/server.py\u003c/code\u003e file, which is part of the \u003ccode\u003eadd_action\u003c/code\u003e Tool component. By manipulating the \u003ccode\u003econtext\u003c/code\u003e argument, a remote attacker can bypass directory restrictions and access unauthorized files. The existence of a published exploit increases the risk of this vulnerability being actively exploited. Defenders should prioritize patching and implementing mitigations to prevent potential data breaches or system compromise.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eThe attacker identifies a vulnerable instance of elinsky execution-system-mcp 0.1.0 running remotely.\u003c/li\u003e\n\u003cli\u003eThe attacker crafts a malicious HTTP request targeting the \u003ccode\u003eadd_action\u003c/code\u003e tool.\u003c/li\u003e\n\u003cli\u003eWithin the HTTP request, the attacker injects a path traversal sequence (e.g., \u003ccode\u003e../\u003c/code\u003e) into the \u003ccode\u003econtext\u003c/code\u003e argument of the \u003ccode\u003e_get_context_file_path\u003c/code\u003e function.\u003c/li\u003e\n\u003cli\u003eThe \u003ccode\u003e_get_context_file_path\u003c/code\u003e function processes the tainted input without proper sanitization, allowing the path traversal sequence to resolve to a file outside of the intended directory.\u003c/li\u003e\n\u003cli\u003eThe server attempts to read the file specified by the attacker-controlled path.\u003c/li\u003e\n\u003cli\u003eSensitive information from the targeted file is read by the server.\u003c/li\u003e\n\u003cli\u003eThe server returns the content of the file, or an error message indicating the file content, to the attacker.\u003c/li\u003e\n\u003cli\u003eThe attacker obtains sensitive information, potentially leading to further exploitation, such as privilege escalation or data exfiltration.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of this vulnerability allows an attacker to read arbitrary files on the server. This could lead to the disclosure of sensitive information, such as configuration files, source code, or user data. The CVSS v3.1 score of 7.3 indicates a high severity, highlighting the potential for significant impact. The lack of specifics regarding victim count and sectors targeted in the source information makes it difficult to quantify the precise scale of potential damage.\u003c/p\u003e\n\u003ch2 id=\"recommendation\"\u003eRecommendation\u003c/h2\u003e\n\u003cul\u003e\n\u003cli\u003eApply any available patches or updates for elinsky execution-system-mcp to address CVE-2026-7319.\u003c/li\u003e\n\u003cli\u003eImplement input validation and sanitization measures to prevent path traversal attacks within the \u003ccode\u003e_get_context_file_path\u003c/code\u003e function.\u003c/li\u003e\n\u003cli\u003eDeploy the Sigma rule provided to detect exploitation attempts by monitoring for suspicious path traversal sequences in HTTP requests to the \u003ccode\u003eadd_action\u003c/code\u003e tool.\u003c/li\u003e\n\u003cli\u003eMonitor web server logs for requests containing path traversal sequences such as \u0026ldquo;../\u0026rdquo; and ensure proper logging of access attempts.\u003c/li\u003e\n\u003c/ul\u003e\n","date_modified":"2026-04-29T10:00:00Z","date_published":"2026-04-29T10:00:00Z","id":"/briefs/2026-04-elinsky-path-traversal/","summary":"Elinsky execution-system-mcp 0.1.0 is vulnerable to path traversal via manipulation of the context argument in the _get_context_file_path function, allowing remote attackers to access sensitive files.","title":"Elinsky execution-system-mcp Path Traversal Vulnerability","url":"https://feed.craftedsignal.io/briefs/2026-04-elinsky-path-traversal/"}],"language":"en","title":"CraftedSignal Threat Feed — Cve-2026-7319","version":"https://jsonfeed.org/version/1.1"}
