CVE-2026-101884
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.47%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
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.
