Summary

Scrapy from 1.4.0 before 2.14.2 contains an unsafe reflection flaw (CWE-470) in RefererMiddleware. The middleware treats a Referrer-Policy response header value that resembles a Python import path as a policy class, imports the named object and calls it. A malicious website can supply a callable such as sys.exit without authentication and terminate a crawler that processes its response.

Description from the CNA

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.
