OpenClaw safeBins stdin-only bypass via sort output and recursive grep flags
Packages
Details
As written in the advisory (Markdown source, shown as plain text).
## 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: `<= 2026.2.17`
- Patched 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`).
