CRITICALPre-NVD 9.39.3—
EchelonGraph scoreMEDIUM confidence

This critical-severity CVE scores 9.3 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.2%, top 85% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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.
