Docling vulnerabilities

In Docling prior to version 2.94.0, unsafe URI and path handling was found in the HTML backend. This vulnerability could allow an attacker to perform unauthorized operations on files or network resources.

A vulnerability in Docling library versions 2.13.0 through 2.74.0 allows XML External Entity (XXE) attacks via parsing malicious USPTO patent XML files. An attacker can read arbitrary files from the server, perform SSRF attacks, or cause denial of service through entity expansion.

A vulnerability in Docling before version 2.91.0 allows Zip Slip attacks during EasyOCR model downloads. An attacker can overwrite arbitrary files, leading to remote code execution, persistent backdoors, or data corruption.

In Docling versions 2.82.0 through 2.90.0, if the HTML backend was explicitly configured for rendering (disabled by default), the Playwright-based rendering feature could allow JavaScript execution and unrestricted network access when processing untrusted HTML documents. An attacker could craft malicious HTML that executes arbitrary JavaScript in the rendering context or makes unauthorized network requests to internal services.
