How to Fix CVE-2026-32921
To remediate this vulnerability, upgrade all affected Openclaw dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
npm install openclaw@2026.3.8
Run the following command in your project directory to verify that all resolved dependencies use the patched release:
npm ls openclaw
How to Check if You Are Affected
To determine whether your Node.js application is affected by CVE-2026-32921, inspect your project dependencies using npm:
npm ls openclaw
Analyze the terminal output to locate any version of Openclaw in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2026.3.8), your application is affected.
Note: The npm ls openclaw command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition, where the product checks the state of a resource before using that resource, but the resource's state can change between the check and the use in a way that invalidates the results of the check. In Openclaw, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

"details" : "OpenClaw's `system.run` approval flow did not bind mutable interpreter-style script operands across approval and execution.\n\nA caller could obtain approval for an execution such as `sh ./script.sh`, rewrite the approved script before execution, and then execute different content under the previously approved command shape. The approved `argv` values remained the same, but the mutable script operand content could drift after approval.\n\nLatest published npm version verified vulnerable: `2026.3.7`\n\nThe initial March 7, 2026 fix in `c76d29208bf6a7f058d2cf582519d28069e42240` added approval binding for shell scripts and a narrow interpreter set, but follow-up maintainer review on March 8, 2026 found that `bun` and `deno` script operands still did not produce `mutableFileOperand` snapshots.\n\nA complete fix shipped on March 9, 2026 in `cf3a479bd1204f62eef7dd82b4aa328749ae6c91`, which binds approved `bun` and `deno run` script operands to on-disk file snapshots and denies post-approval script drift before execution.\n\n## Affected Packages / Versions\n\n- Package: `openclaw` (npm)\n- Affected versions: `<= 2026.3.7`\n- Patched version: `2026.3.8`\n\n## Fix Commit(s)\n\n- `c76d29208bf6a7f058d2cf582519d28069e42240`\n- `cf3a479bd1204f62eef7dd82b4aa328749ae6c91`\n\n## Release Verification\n\n- npm `2026.3.7` remains vulnerable.\n- npm `2026.3.8` contains the completed fix.\n\nThanks @tdjackey for reporting.",
