CVE-2026-101882: Incomplete List of Disallowed Inputs in OpenClaw OpenClaw Windows Node
OpenClaw Windows Node versions before 2026.7.1 have a vulnerability in the system.execApprovals.set function that allows remote callers to add overly permissive execution rules. This flaw involves incomplete validation of inputs, permitting wildcard-executable rules and the use of abusable system binaries such as mshta, rundll32, and certutil. Exploitation enables arbitrary command execution on the Windows host without operator checks or user prompts.
AI Analysis
Technical Summary
CVE-2026-101882 is a high-severity vulnerability affecting OpenClaw Windows Node prior to version 2026.7.1. The issue stems from incomplete validation in the system.execApprovals.set function, which accepts wildcard-executable rules and allows the use of certain system binaries known for abuse. Remote attackers with limited privileges can leverage this to add broad allow rules, enabling arbitrary command execution via system.run without requiring operator approval or user interaction.
Potential Impact
An attacker with remote access and limited privileges can execute arbitrary commands on the affected Windows host without operator checks or user prompts. This can lead to full system compromise or unauthorized actions, significantly impacting system security and integrity.
Mitigation Recommendations
A fix is available in OpenClaw Windows Node version 2026.7.1. Users should upgrade to this version or later to remediate the vulnerability. No additional mitigation steps are indicated in the provided data.
