CVE-2026-28363Network attack vector

Approval bypass via abbreviated GNU sort options

Published Feb 27, 2026 · Updated Feb 27, 2026

Command injection in OpenClaw before 2026.2.23 allows remote authenticated users to execute programs without approval through sort. The tools.exec.safeBins sort profile matched denied long options only as exact strings and accepted unknown inline-valued abbreviations. Reachability requires allowlist security, ask-on-miss approval, and sort in safeBins; successful use runs an external program as the OpenClaw process.
