CVE-2026-53853 Details
Description
OpenClaw before 2026.5.12 contains an argument pattern validation bypass in the exec allowlist that allows attackers to execute disallowed arguments for allowlisted executables on Linux and macOS systems. Attackers can bypass configured argPattern restrictions by directly invoking allowlisted executables with unrestricted arguments, potentially enabling unauthorized file access, network access, or command execution.
A vulnerability in OpenClaw versions prior to 2026.5.12 allows for an argument pattern validation bypass in the exec allowlist. This issue enables attackers to execute disallowed arguments for allowlisted executables on Linux and macOS systems. The vulnerability arises because the exec allowlist skips configured argument pattern checks, allowing unrestricted arguments to be passed to allowlisted executables. This could lead to unauthorized file access, network access, or command execution.
Users are advised to upgrade to OpenClaw version 2026.5.12 or later. Before upgrading, review exec allowlist entries that combine an executable path with argument patterns, particularly for tools that act as interpreters or can spawn subprocesses.
