CVSS: 7.5EPSS: 0%CPEs: 2EXPL: 0CVE-2024-1968 – Authorization Header Leakage in scrapy/scrapy on Scheme Change Redirects
https://notcve.org/view.php?id=CVE-2024-1968
20 May 2024 — In scrapy/scrapy, an issue was identified where the Authorization header is not removed during redirects that only change the scheme (e.g., HTTPS to HTTP) but remain within the same domain. This behavior contravenes the Fetch standard, which mandates the removal of Authorization headers in cross-origin requests when the scheme, host, or port changes. Consequently, when a redirect downgrades from HTTPS to HTTP, the Authorization header may be inadvertently exposed in plaintext, leading to potential sensitive... • https://github.com/scrapy/scrapy/commit/1d0502f25bbe55a22899af915623fda1aaeb9dd8 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVSS: 7.5EPSS: 0%CPEs: 1EXPL: 0CVE-2024-3574 – Authorization Header Leak During Cross-Domain Redirect in scrapy/scrapy
https://notcve.org/view.php?id=CVE-2024-3574
16 Apr 2024 — In scrapy version 2.10.1, an issue was identified where the Authorization header, containing credentials for server authentication, is leaked to a third-party site during a cross-domain redirect. This vulnerability arises from the failure to remove the Authorization header when redirecting across domains. The exposure of the Authorization header to unauthorized actors could potentially allow for account hijacking. En la versión 2.10.1 de scrapy, se identificó un problema por el cual el encabezado de Autoriz... • https://github.com/scrapy/scrapy/commit/5bcb8fd5019c72d05c4a96da78a7fcb6ecb55b75 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

16 Apr 2024 — The scrapy/scrapy project is vulnerable to XML External Entity (XXE) attacks due to the use of lxml.etree.fromstring for parsing untrusted XML data without proper validation. This vulnerability allows attackers to perform denial of service attacks, access local files, generate network connections, or circumvent firewalls by submitting specially crafted XML data.

https://notcve.org/view.php?id=CVE-2024-1892
28 Feb 2024 — A Regular Expression Denial of Service (ReDoS) vulnerability exists in the XMLFeedSpider class of the scrapy/scrapy project, specifically in the parsing of XML content. By crafting malicious XML content that exploits inefficient regular expression complexity used in the parsing process, an attacker can cause a denial-of-service (DoS) condition. This vulnerability allows for the system to hang and consume significant resources, potentially rendering services that utilize Scrapy for XML processing unresponsiv... • https://github.com/scrapy/scrapy/commit/479619b340f197a8f24c5db45bc068fb8755f2c5 • CWE-1333: Inefficient Regular Expression Complexity •

https://notcve.org/view.php?id=CVE-2021-41125
06 Oct 2021 — Scrapy is a high-level web crawling and scraping framework for Python. If you use `HttpAuthMiddleware` (i.e. the `http_user` and `http_pass` spider attributes) for HTTP authentication, all requests will expose your credentials to the request target. This includes requests generated by Scrapy components, such as `robots.txt` requests sent by Scrapy when the `ROBOTSTXT_OBEY` setting is set to `True`, or as requests reached through redirects. Upgrade to Scrapy 2.5.1 and use the new `http_auth_domain` spider at... • http://doc.scrapy.org/en/latest/topics/downloader-middleware.html#module-scrapy.downloadermiddlewares.httpauth • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-522: Insufficiently Protected Credentials •

05 Sep 2017 — Scrapy 1.4 allows remote attackers to cause a denial of service (memory consumption) via large files because arbitrarily many files are read into memory, which is especially problematic if the files are then individually written in a separate thread to a slow storage resource, as demonstrated by interaction between dataReceived (in core/downloader/handlers/http11.py) and S3FilesStore.
