CVE-2026-31996 PUBLISHED

OpenClaw < 2026.2.19 - safeBins stdin-only bypass via sort output and recursive grep flags

Assigner: VulnCheck
Reserved: 10.03.2026 Published: 19.03.2026 Updated: 19.03.2026

OpenClaw versions prior to 2026.2.19 tools.exec.safeBins contains an input validation bypass vulnerability that allows attackers to execute unintended filesystem operations through sort output flags or recursive grep flags. Attackers with command execution access can leverage sort -o flag for arbitrary file writes or grep -R flag for recursive file reads, circumventing intended stdin-only restrictions.
