GHSA-8G75-Q649-6PV6

Vulnerability from github – Published: 2026-03-12 14:21 – Updated: 2026-04-06 22:37

Summary

OpenClaw's system.run approvals did not bind mutable script operands across approval and execution

Details

OpenClaw's system.run approval flow did not bind mutable interpreter-style script operands across approval and execution.

A 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.

Latest published npm version verified vulnerable: 2026.3.7

The 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.

A 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.

Affected Packages / Versions

Package: openclaw (npm)
Affected versions: <= 2026.3.7
