CVE-2026-105782 · Scrapy: Arbitrary Module Import via Referrer-Policy Header in RefererMiddleware

This page contains facts from public vulnerability sources. Check the original advisory before updating.

Scrapy is a high-level web crawling and scraping framework for Python. From 1.4.0 until 2.14.2, RefererMiddleware in scrapy/spidermiddlewares/referer.py treated a Referrer-Policy response-header value that resembled a Python import path as a referrer policy class, imported the referenced object, and called it. A malicious website could supply a callable such as sys.exit and terminate a crawler processing the response. This issue is fixed in version 2.14.2.
