CVE-2026-61738
SOCFortress CoPilot: Arbitrary Host File Write as Root via Path Traversal in the ScoutSuite GCP Report Upload (RCE)
What happened?
SOCFortress CoPilot focuses on providing a single pane of glass for all your security operations needs. Prior to 0.1.77, `POST /api/scoutsuite/generate-gcp-report` in `backend/app/integrations/scoutsuite/routes/scoutsuite.py` admits admin and analyst users and validates the uploaded content as `GCPScoutSuiteJSON`, but passes raw `file.filename` from the multipart header to `save_file_to_directory` in `backend/app/integrations/scoutsuite/services/scoutsuite.py`. The writer combines this filename with `scoutsuite-report` using `os.path.join` without sanitization or a resolved-path containment check. A traversal filename therefore writes the supplied JSON outside the intended report directory. In the reported root-running backend, the researcher demonstrated root-owned writes outside that directory and into the application source directory. This permits host-file overwrite subject to the accepted JSON-content constraint and can disrupt application operation; the demonstrated primitive does not establish unrestricted executable contents or unconditional cross-tenant confidentiality loss. Version 0.1.77 removes caller-controlled filenames from the affected route; unrestricted-content and direct-code-execution claims require separate curator reconciliation.
Affected software and versions
| Software | Version information | Fixed version |
|---|---|---|
| CoPilotsocfortress | affected: < 0.1.77 | See vendor advisory |
Version information comes from the source record and can include unaffected products and exceptions. Distribution packages may contain backported fixes: an older upstream version alone does not prove a server is affected.
Is it being exploited?
This CVE was not listed in the CISA catalogue at our last retrieval. This does not establish that exploitation is absent.
How to respond
- Confirm the product, installed package version, and any configuration requirements in the vendor advisory.
- Follow the vendor’s remediation or workaround guidance in the references below. Structured fixed-version data is unavailable here; the publisher’s description may include a fix or workaround.
- Restart affected services if required, then verify the running version. Known exploitation may warrant investigation as well as patching.
