CVE-2026-48499 Details
Description
Activepieces is an open source AI workflow automation platform. Prior to 0.84.0, an unsanitized path segment in the Code piece sandbox can let an authenticated flow author reach read-write cached flow and code files belonging to other tenants on the same worker, exposing embedded data and allowing modified code to execute on a victim tenant's next flow run. This issue is fixed in version 0.84.0.
A vulnerability in Activepieces versions prior to 0.84.0 allows an authenticated flow author to access and modify cached flow and code files of other tenants on the same worker. This is due to an unsanitized path segment in the Code piece sandbox, which can be exploited to read-write cached files, exposing embedded data and enabling modified code to execute in the victim tenant's environment during the next flow run.
Users can upgrade to Activepieces version 0.84.0 or later. If an immediate upgrade is not possible, switch to the V8 isolate execution mode by setting 'AP_EXECUTION_MODE=SANDBOX_CODE_ONLY' or 'SANDBOX_CODE_AND_PROCESS' on the worker. This will remove filesystem access from Code pieces, although it requires rewriting any Code piece that depends on Node built-ins like 'child_process' or 'fs'.
