CVE-2026-25996: Inspektor Gadget uses unsanitized ANSI Escape Sequences In `columns` Output Mode

• Severity: critical (CVSS 9.8 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.6% probability of exploitation in the next 30 days
• Public exploit or detection template: yes

• Weakness: CWE-150

Description

Inspektor Gadget is a set of tools and framework for data collection and system inspection on Kubernetes clusters and Linux hosts using eBPF. String fields from eBPF events in columns output mode are rendered to the terminal without any sanitization of control characters or ANSI escape sequences. Therefore, a maliciously forged – partially or completely – event payload, coming from an observed container, might inject the escape sequences into the terminal of ig operators, with various effects. The columns output mode is the default when running ig run interactively.
