OpenClaw before 2026.4.10 contains an insufficient environment variable denylist vulnerability in its exec environment policy that allows operator-supplied overrides of high-risk interpreter startup variables including VIMINIT, EXINIT, LUA_INIT, and HOSTALIASES. Attackers can exploit this by manipulating these environment variables to influence downstream execution behavior or network connectivity.
