Debian Python-Scrapy vulnerabilities

CVE-2025-6176 [HIGH] CVE-2025-6176: python-scrapy - Scrapy versions up to 2.13.2 are vulnerable to a denial of service (DoS) attack ... Scrapy versions up to 2.13.2 are vulnerable to a denial of service (DoS) attack due to a flaw in its brotli decompression implementation. The protection mechanism against decompression bombs fails to mitigate the brotli variant, allowing remote servers to crash clients with less than 80GB of available memory. This occurs because brotli can achieve extremely high

CVE-2024-3572 [HIGH] CVE-2024-3572: python-scrapy - The scrapy/scrapy project is vulnerable to XML External Entity (XXE) attacks due... 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.

CVE-2024-1968 [HIGH] CVE-2024-1968: python-scrapy - In scrapy/scrapy, an issue was identified where the Authorization header is not ... 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. Consequentl

CVE-2024-3574 [HIGH] CVE-2024-3574: python-scrapy - In scrapy version 2.10.1, an issue was identified where the Authorization header... 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

CVE-2024-1892 [MEDIUM] CVE-2024-1892: python-scrapy - A Regular Expression Denial of Service (ReDoS) vulnerability exists in the XMLFe... 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 vulnerabil

CVE-2022-0577 [MEDIUM] CVE-2022-0577: python-scrapy - Exposure of Sensitive Information to an Unauthorized Actor in GitHub repository ... Exposure of Sensitive Information to an Unauthorized Actor in GitHub repository scrapy/scrapy prior to 2.6.1. Scope: local bookworm: resolved (fixed in 2.6.1-1) bullseye: resolved (fixed in 2.4.1-2+deb11u1) forky: resolved (fixed in 2.6.1-1) sid: resolved (fixed in 2.6.1-1) trixie: resolved (fixed in 2.6.1-1)

CVE-2021-41125 [MEDIUM] CVE-2021-41125: python-scrapy - Scrapy is a high-level web crawling and scraping framework for Python. If you us... 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 `

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/htt
