CVE intelligence and bounded remediation

CVE-2025-27519 — Cognita is a RAG (Retrieval Augmented Generation) Framework for building modular, open source applications for production by TrueFoundry

Critical CVSS 9.3

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.

Matched remediation archetype

Path traversal, unsafe upload, and file handling

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace untrusted filenames, archive entries, URLs, and path segments into read, write, include, extraction, and upload operations.
  • Identify filesystem roots, mount permissions, symbolic-link behavior, archive handling, and whether uploaded content is web-accessible or executable.
  • Review canonicalization and containment checks across supported operating systems and storage backends.

Remediate safely

  • Generate server-side storage identifiers and resolve paths beneath a fixed root using filesystem-aware containment checks.
  • Reject absolute, parent-relative, alternate-separator, device, link, and archive entries that escape the intended root.
  • Store uploads outside executable or served paths, validate type and size, and use private atomic temporary files.
