CVE-2026-48499
CRITICALActivepieces: Cross-tenant data exposure and code injection via the Code piece sandbox cache
Title source: cnaDescription
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.
