Arbitrary JavaScript execution via hook module traversal
Published Mar 5, 2026 · Updated Mar 5, 2026
Path traversal in OpenClaw 2.0.0-beta3 through 2026.2.13 allows local users to execute JavaScript with gateway privileges. The hooks.mappings[].transform.module value reached dynamic import after path resolution accepted absolute paths and relative paths outside the transforms directory. Exploitation requires configuration-write access, a malicious local module, and an authenticated hook request; the module then runs as the gateway process.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
