CVE-2026-101884 Details
Description
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.
A vulnerability exists in OpenClaw Windows Node versions prior to 2026.7.1 due to an incomplete environment variable sanitizer in the 'system.run' feature. The sanitizer fails to block certain variables, including GIT_CONFIG_*, DOTNET_STARTUP_HOOKS, and JAVA_TOOL_OPTIONS. This oversight allows attackers with gateway or agent access to manipulate these variables and inject code into allowlisted tools such as git, dotnet, or java, leading to arbitrary code execution.
Users can update to OpenClaw Windows Node version 2026.7.1 or later, where this vulnerability has been addressed.
