Vulnerability in docling (CVE-2026-105745)
Summary
Vulnerability in docling (CVE-2026-105745). Successful exploitation can lead to full system takeover. Exploitable via docling.. Mitigation: upgrade to 2.131.0 or later.
Original description
The description as published by the source.
Summary
allow_external_plugins=False (the default, and the CLI default) is meant to restrict docling to its own model plugins. However, docling's plugin factories call pluggy's load_setuptools_entrypoints(), which imports every module registered under docling's plugin entry-point group. Only afterwards does docling filter out modules outside the docling. namespace. Import-time code in any installed third-party plugin therefore runs even though external plugins are disabled.
Details
In docling/models/factories/base_factory.py, load_from_plugins() loads all entry points first and applies the allow_external_plugins check only to the already-imported modules. The CLI creates these factories when it starts, so running docling imports every registered plugin module. A log message says the plugin "will not be loaded", although its module has already been imported.
Affected configurations
Environments in which a package registering a docling plugin entry point is installed, for example an unvetted or compromised dependency, and which rely on allow_external_plugins=False to keep that code from running.
Impact
Execution of a third-party plugin module's import-time code in the docling process, contrary to the documented behaviour of allow_external_plugins=False.
Patches
Fixed in docling 2.131.0 by #4413. Plugin entry points are now filtered by module name before they are loaded, so wit…
