CVE-2026-25996Public exploitNetwork attack vector

Terminal output manipulation via unescaped event strings

Published Feb 12, 2026 · Updated Feb 12, 2026

Terminal escape injection in Inspektor Gadget before 0.49.1 allows attackers to alter an operator's displayed event output. TextColumnsFormatter.buildFixedString renders string fields from eBPF events without quoting control characters, so the terminal interprets attacker-supplied ANSI sequences. An observed container must forge an event payload while an operator runs ig interactively with the default columns output; demonstrated impact includes inserting, deleting, or overwriting displayed log lines.
