Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

OpenClaw是OpenClaw开源的一个智能人工助理。 OpenClaw 2026.3.31之前版本存在代码问题漏洞，该漏洞源于不完整的host-env-security-policy.json未能限制编译器二进制环境变量，允许不受信任的模型通过环境覆盖替换CC、CXX、CARGO_BUILD_RUSTC和CMAKE_C_COMPILER。具有批准的主机执行请求的攻击者可以在构建过程中覆盖编译器二进制文件以执行任意代码。

Vulnerability Title
OpenClaw < 2026.3.31 - Compiler Binary Substitution via Environment Variable Override in Host Execution Policy
Source: CVE Program / CVE List V5
Vulnerability Description
OpenClaw before 2026.3.31 contains an incomplete host-env-security-policy.json that fails to restrict compiler binary environment variables, allowing untrusted models to substitute CC, CXX, CARGO_BUILD_RUSTC, and CMAKE_C_COMPILER via environment overrides. Attackers with approved host-exec requests can override compiler binaries to execute arbitrary code during build processes.
