Background

Scrapy is an open-source web crawling framework written in Python. It provides a high-level API for efficiently scraping websites and extracting structured data. Scrapy is widely used for web scraping and data mining tasks due to its flexibility and scalability. However, a vulnerability has been discovered in scrapy that allows for incorrect authorization and exposure of sensitive information to an unauthorized actor.

Vulnerability Detail

The vulnerability in scrapy arises when manually defining cookies on a Request object that receives a redirect response. In such cases, the new Request object scheduled to follow the redirect retains the user-defined cookies, regardless of the target domain. This can lead to unauthorized access to sensitive information. The vulnerability has a CVSS score of 6.5, indicating a moderate severity level. The impact of this vulnerability includes potential data breaches and unauthorized access to user-specific information.

How To Fix

Latest published version: 2.19.0 as of 22 Oct 2026

pip install --upgrade "scrapy==2.19.0"

Upgrading to it may include breaking changes; the versions below are the minimum fixed release for this vulnerability.

If you can't move to the latest

The minimum fixed version depends on the release line you run.

< 1.8.2 1.8.2

Workaround

If upgrading is not feasible, a workaround is to set cookies using a list of dictionaries instead of a single dictionary when defining cookies on a Request object. Each cookie should have the appropriate domain set. Additionally, cookies can be disabled altogether or limited to trusted domains using the appropriate Scrapy settings.

Conclusion

The vulnerability in scrapy allows for incorrect authorization and exposure of sensitive information to unauthorized actors. To mitigate this vulnerability, it is crucial to upgrade to the latest secure version of Scrapy (2.6.0 or higher). Alternatively, upgrading to Scrapy 1.8.2 is also an option. If upgrading is not feasible, workarounds such as setting cookies using a list of dictionaries or disabling cookies can be implemented.
