CVE-2026-61708: SOCFortress CoPilot data store upload allows cross-tenant object overwrite

Source: NVD(opens in a new tab)
Identifier: CVE-2026-61708
Published: October 30, 2026
Record updated: October 30, 2026

Known exploitation: Not listed in the CISA Known Exploited Vulnerabilities catalog at the last check.

Summary

Prior to version 0.1.76, SOCFortress CoPilot's `POST /api/agent_data_store/upload` endpoint in `backend/app/data_store/data_store_routes.py` let `customer_user` callers choose `bucket_name` and `object_name` with no allowlist, tenant prefix, ownership check or content restriction, so existing objects of any tenant could be overwritten. Targets include Sysmon configs distributed to Windows endpoints, server-rendered case report templates, and case and Velociraptor forensic artifacts, letting a lowest-privilege user tamper with cross-tenant evidence, blind endpoint telemetry or poison report templates. Sibling list, download and delete routes stay restricted to admin and analyst roles.

Mitigation

Fixed in version 0.1.76.
