PYSEC-2026-4299 Scrapy: Arbitrary Module Import via Referrer-Policy Header in RefererMiddleware

Impact Since version 1.4.0, Scrapy respects the Referrer-Policy response header to decide whether and how to set a Referer header on follow-up requests. If the header value looked like a valid Python import path, Scrapy would import the referenced object and call it, assuming it referred to a...

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,...

CVE-2026-105782

The Scrapy web crawling framework (versions 1.4.0 through 2.14.1) is vulnerable to arbitrary module import via the Referrer-Policy response header. The RefererMiddleware in scrapy/spidermiddlewares/referer.py incorrectly treats values resembling Python import paths as referrer policy classes, imp...
