Affected packages
• npm openclaw: < 2026.2.19 → fixed in 2026.2.19
Description
Summary
`tools.exec.safeBins` could be bypassed for filesystem access when `sort` output flags (`-o` / `--output`) or recursive `grep` flags were allowed through safe-bin execution paths.
Affected Packages / Versions
• Package: `openclaw` (npm)
• Affected versions: `= 2026.2.19`
• Latest published version at triage time: `2026.2.17`
Impact
In deployments that enabled `tools.exec.safeBins`, an attacker with access to command execution flows could turn intended stdin-only safe-bin usage into file writes (`sort -o`) or recursive file reads (`grep -R`).
