CVE-2026-101884: Incomplete List of Disallowed Inputs in OpenClaw OpenClaw Windows Node
OpenClaw Windows Node before 2026.7.1 contains an incomplete environment-variable sanitizer in system.run that fails to block GIT_CONFIG_*, DOTNET_STARTUP_HOOKS, and JAVA_TOOL_OPTIONS variables. Attackers with gateway or agent access can supply these variables to allowlisted tools like git, dotnet, or java to load attacker-controlled code and achieve arbitrary code execution.
AI Analysis
Technical Summary
CVE-2026-101884 describes a vulnerability in OpenClaw Windows Node prior to version 2026.7.1 where the environment-variable sanitizer in system.run does not block specific environment variables (GIT_CONFIG_*, DOTNET_STARTUP_HOOKS, JAVA_TOOL_OPTIONS). These variables can be leveraged by allowlisted tools like git, dotnet, or java to load malicious code supplied by an attacker with gateway or agent access, resulting in arbitrary code execution.
Potential Impact
An attacker with gateway or agent access can supply specially crafted environment variables to allowlisted tools, enabling them to execute arbitrary code on the affected system. This can lead to full compromise of the node running OpenClaw Windows Node prior to 2026.7.1.
Mitigation Recommendations
A fix is available in OpenClaw Windows Node version 2026.7.1 and later. Users should upgrade to version 2026.7.1 or newer to remediate this vulnerability. No vendor advisory content was provided to indicate alternative mitigations or temporary fixes.
