An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-42453 exists.\n\nAffected product: Termix-SSH Termix. 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-2026-42453/ (Markdown: https://insights.sbomify.com/CVE-2026-42453/index.md)","id":"CVE-2026-42453","markdown":"https://insights.sbomify.com/CVE-2026-42453/index.md","name":"CVE-2026-42453","record":{"aliases":["GHSA-rvg4-7vvq-9c2w"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Server management platform","requires_auth":"none","summary":"Attackers can execute arbitrary commands on remote SSH hosts via Termix file manager endpoints due to improper shell command construction.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-77","name":"Improper Neutralization of Special Elements used in a Command"}],"description":"Termix is a web-based server management platform with SSH terminal, tunneling, and file editing capabilities.
