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...

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...

Apache Airflow Task SDK Callback deserialization can import arbitrary modules in the scheduler

Apache Airflow 3.3.0 moved human-in-the-loop tasks from the triggerer to a new awaitinginput task state swept by the scheduler. That sweep deserializes the task instance's nextkwargs without an allow-list, so a Dag author — who controls that value through the task execution API — can cause an...
