CVE-2026-31997
|
| Summary | OpenClaw: system.run approvals did not bind PATH-token executable identity, enabling post-approval executable rebind ### Summary For `host=node` runs, approvals validated command context but did not pin executable identity for non-path-like `argv[0]` tokens (for example `tr`). If PATH resolution changed after approval, execution could run a different binary. ### Impact A previously approved action could execute a different executable than the operator approved. ### Fix Node `system.run` approvals now require immutable `systemRunPlan` data, and path-token commands are pinned to canonical executable identity (`realpath`) across approval and execution. ### Affected and Patched Versions - Affected: `<= 2026.2.26` - Patched: `2026.3.1` |
