CVE-2022-36006Public exploitNetwork attack vector

Authenticated code execution via unrestricted Oj.load deserialization

Published Aug 14, 2022 · Updated Apr 23, 2025

Insecure deserialization in Arvados Workbench 1 before 2.4.2 allows remote authenticated users to execute arbitrary code via JSON filters. The search endpoint passes its user-controlled filters parameter to Oj.load without a restrictive mode, permitting construction of arbitrary Ruby objects and gadget-chain execution. A valid session and CSRF token are required, and successful exploitation runs code with the Workbench service's host privileges.
