Incorrect Authorization and Exposure of Sensitive Information to an Unauthorized Actor in scrapy
GitHub lists this reviewed advisory for scrapy, scrapy. Published version ranges and source prerequisites are shown below; this is not an inspection of a visitor’s application.
This report has not inspected your inventory, configuration, deployed build, reachability or evidence. A catalog listing and a severity score do not establish exposure or compromise.
01 / Meaning
Why it matters
Published affected context helps an owner decide what evidence to gather. This report has not examined your application.
6.5 medium
GitHub source severity; exploitability and local consequence require separate evidence.
As of · GitHub Advisory Database
4 MEDIUM (2.0)
nvd@nist.gov severity; no combined Null risk score.
8.8 HIGH (3.0)
security@huntr.dev severity; no combined Null risk score.
6.5 MEDIUM (3.1)
nvd@nist.gov severity; no combined Null risk score.
02 / Applicability
The affected context
Affected versions, configuration prerequisites and known exclusions are public. Confirm each one against the deployed service.
scrapy
source listed< 1.8.2
### Impact If you manually define cookies on a `Request` object, and that `Request` object gets a redirect response, the new `Request` object scheduled to follow the redirect keeps those user-defined cookies, regardless of the target domain. ### Patches Upgrade to Scrapy 2.6.0, which resets cookies when creating `Request` objects to follow redirects¹, and drops the ``Cookie`` header if manually-defined if the redirect target URL domain name does not match the source URL domain name². If you are using Scrapy 1.8 or a lower version, and upgrading to Scrapy 2.6.0 is not an option, you may upgrade to Scrapy 1.8.2 instead. ¹ At that point the original, user-set cookies have been processed by the cookie middleware into the global or request-specific cookiejar, with their domain restricted to the domain of the original URL, so when the cookie middleware processes the new (redirect) request it will incorporate those cookies into the new request as long as the domain of the new request matches the domain of the original request. ² This prevents cookie leaks to unintended domains even if the cookies m

03 / Response
What to do next
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. NIST National Vulnerability Database
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
04 / Limits
What this report cannot establish
- Customer inventory, deployment, reachability and exploitation have not been inspected.
- NVD lastModified does not establish freshness of every associated CPE record.
05 / Provenance
Sources you can inspect
Each assertion retains its source. Mirrored records may repeat one underlying publisher; additional links are not independent corroboration.
