EchelonGraph scoreMEDIUM confidence

This critical-severity CVE scores 9.3 under NVD CVSS v3. EPSS exploit probability: 1.3%, top 33% 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).

Cognita is a RAG (Retrieval Augmented Generation) Framework for building modular, open source applications for production by TrueFoundry. A path traversal issue exists at /v1/internal/upload-to-local-directory which is enabled when the Local env variable is set to true, such as when Cognita is setup using Docker. Because the docker environment sets up the backend uvicorn server with auto reload enabled, when an attacker overwrites the /app/backend/__init__.py file, the file will automatically be reloaded and executed. This allows an attacker to get remote code execution in the context of the Docker container. This vulnerability is fixed in commit a78bd065e05a1b30a53a3386cc02e08c317d2243.
