Docling simplifies document processing by parsing diverse formats and providing integrations with the generative AI ecosystem. From 2.73.0 until 2.91.0, he LaTeX backend's handling of \includegraphics, \input, and \include commands lacked path containment validation. Attackers could craft malicious LaTeX documents with path traversal sequences to read arbitrary files from the file system accessible to the process, include sensitive files in the converted document output, or potentially access configuration files, credentials, or other sensitive data This vulnerability is fixed in 2.91.0.

GHSA-2j5p-7p5m-cvqr — Docling: Potential Path Traversal via LaTeX \includegraphics and \input Commands

Affected: PyPI: docling

### Impact The LaTeX backend's handling of `\includegraphics`, `\input`, and `\include` commands lacked path containment validation. Attackers could craft malicious LaTeX documents with path traversal sequences (e.g., `../../../etc/passwd`) to: - Read arbitrary files from the file system accessible to the process - Include sensitive files in the converted document output - Potentially access configuration files, credentials, or other sensitive data

### Patches Fixed in version 2.91.0. The fix implements strict path validation using `Path.resolve().is_relative_to()` to ensure all resolved paths remain within the base document directory. Attempts to traverse outside the base directory are logged and blocked.

### Workarounds Avoid processing untrusted LaTeX documents. If processing is necessary, run in a sandboxed environment with restricted file system access.

### References - Fix release: [v2.91.0](https://github.com/docling-project/docling/releases/tag/v2.91.0)
