Description
Summary
OpenClaw exec allowlist/safeBins policy could be bypassed with attached short-option payloads (for example sort -o/tmp/poc), enabling file-write operations while still satisfying safeBins checks.
Affected Packages / Versions
- Package:
openclaw(npm) - Affected versions:
<= 2026.2.17 - Latest published vulnerable version:
2026.2.17 - Patched in:
2026.2.19
Impact
When tools.exec.security=allowlist and tools.exec.safeBins included affected binaries, attached short-option payloads could bypass safeBins argument validation and permit file-write behavior that should have been denied.

How to fix
Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.

Weakness
CWE-184: Incomplete List of Disallowed Inputs
The product implements a protection mechanism that relies on a list of inputs (or properties of inputs) that are not allowed by policy or otherwise require other action to neutralize before additional processing takes place, but the list is incomplete.
How to prevent it
- Implementation: Do not rely exclusively on detecting disallowed inputs. There are too many variants to encode a character, especially when different environments are used, so there is a high likelihood of missing some variants. Only use detection of disallowed inputs as a mechanism for detecting suspicious activity. Ensure that you are using other protection mechanisms that only identify "good" input - such as lists of allowed inputs - and ensure that you are properly encoding your outputs.
