An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-0757 in the wild and no public exploit code.\n\nAffected product: MCP Manager for Claude Desktop. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-0757/ (Markdown: https://insights.sbomify.com/CVE-2026-0757/index.md)","id":"CVE-2026-0757","markdown":"https://insights.sbomify.com/CVE-2026-0757/index.md","name":"CVE-2026-0757","record":{"aliases":["GHSA-fm26-rhvj-jjw8"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["code_execution","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Claude Desktop MCP Manager","requires_auth":"none","summary":"Remote attackers can escape the sandbox and execute arbitrary code via command injection in MCP Manager for Claude Desktop.","user_interaction":"required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"zdi","cpe":[],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"MCP Manager for Claude Desktop execute-command Command Injection Sandbox Escape Vulnerability. This vulnerability allows remote attackers to bypass the sandbox on affected installations of MCP Manager for Claude Desktop. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.\n\nThe specific flaw exists within the processing of MCP config objects. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to escape the sandbox and execute arbitrary code in the context of the current process at medium integrity.
