{"id":"CVE-2026-61708","published":"2026-10-30T15:16:52.793","lastModified":"2026-10-30T17:13:54.187","description":"SOCFortress CoPilot focuses on providing a single pane of glass for all your security operations needs. Prior to 0.1.76, `POST /api/agent_data_store/upload` in `backend/app/data_store/data_store_routes.py` permits `customer_user` callers to choose `bucket_name` and `object_name` without an allowlist, tenant prefix, ownership check or content restriction. The only file check requires a nonempty filename. The operations in `backend/app/data_store/data_store_operations.py` create missing buckets and upsert objects, allowing existing objects belonging to any tenant to be overwritten. Targets include `sysmon-configs/<customer_code>/sysmon_config.xml` distributed to managed Windows endpoints, `copilot-case-report-templates/<name>` rendered server-side, and case evidence or forensic artifacts under `copilot-cases/<case_id>/<file>` and `velociraptor-artifacts/<agent_id>/<flow_id>/<file>`. A lowest-privilege user can tamper with cross-tenant evidence, blind endpoint telemetry, poison report templates for later code execution, plant data or exhaust storage. Sibling list, download and delete routes remain restricted to admin/analyst; the exposed operation is the upload write path. This issue is fixed in version 0.1.76.","cvssScore":8.5,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:H/A:L","cwes":["CWE-284","CWE-639","CWE-862"],"vendors":[],"products":[],"references":[{"url":"https://github.com/socfortress/CoPilot/commit/2d090bc07a109eefbdf9ed22dc67b0c93922d9ca","tags":[]},{"url":"https://github.com/socfortress/CoPilot/pull/937","tags":[]},{"url":"https://github.com/socfortress/CoPilot/security/advisories/GHSA-6j26-wcv6-gp3f","tags":[]},{"url":"https://github.com/socfortress/CoPilot/tree/v0.1.76","tags":[]}],"exploitRefs":[{"url":"https://github.com/socfortress/CoPilot/commit/2d090bc07a109eefbdf9ed22dc67b0c93922d9ca","tags":[]},{"url":"https://github.com/socfortress/CoPilot/pull/937","tags":[]},{"url":"https://github.com/socfortress/CoPilot/security/advisories/GHSA-6j26-wcv6-gp3f","tags":[]},{"url":"https://github.com/socfortress/CoPilot/tree/v0.1.76","tags":[]}],"hasPoc":true,"ai":null}
