          "details": "This flaw only materializes when a user interactively lists an attacker‑supplied archive (cpio -it) in a terminal that interprets ANSI control sequences, and its effect is limited to forged display output/terminal control with no confidentiality impact and no ability to modify files or execute code. When output is redirected, piped to tools that do not interpret escapes, or reviewed in non‑interactive contexts, the injected sequences are rendered inert, eliminating practical impact. Given the required user interaction, lack of privilege escalation, and integrity impact confined to misleading listings, this issue is suitable to deprioritize in managed enterprise server and VM environments.",
