CVE-2026-31996
OpenClaw safeBins stdin-only bypass via sort output and recursive grep flags
Impact
## 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`). ## Fix Commit(s) - `2c05cbb43e48ebad03626d3125746fb1b9a8520f` Found using [MCPwner](https://github.com/Pigyon/MCPwner) Thanks @nedlir for reporting.
