CVE-2026-31999
CpenClaw's ACPX Windows wrapper shell fallback allowed cwd injection in specific paths
描述
### Summary On Windows ACPX paths, wrapper resolution for `.cmd`/`.bat` could fall back to shell execution in ways that allowed `cwd` influence to alter execution behavior. ### Impact In affected Windows ACPX configurations, this could enable command execution integrity loss through cwd-influenced wrapper resolution. ### Fix Wrapper resolution now prefers explicit PATH/PATHEXT entrypoint resolution and unwrapped Node/EXE execution, with strict fail-closed handling enabled by default for unresolvable wrapper cases. ### Affected and Patched Versions - Affected: `>= 2026.2.26, < 2026.3.1` - Patched: `2026.3.1`
