scrapy 信息泄露漏洞

Scrapy is a free and open source web crawler framework written in Python. An information disclosure vulnerability exists in scrapy that stems from the fact that the authorization header may be inadvertently exposed in plaintext, leading to the disclosure of potentially sensitive information...

Information Disclosure

scrapy is vulnerable to Information Disclosure. The vulnerability is due to redirects ignoring scheme specific proxy settings, which results in http / https schemes using the wrong proxy if the proxy was configured to be scheme specific...

Authorization Header Leakage

scrapy is vulnerable to Authorization Header Leakage. The vulnerability is due to including the authorization header during redirects, where the domain remains the same but the scheme or port changes...

Open Redirect

scrapy is vulnerable to Open Redirect. The vulnerability is due to indiscriminate handling of redirects across different URL schemes, which can result in redirecting requests to potentially malicious destinations, such as local files, malicious FTP servers, or S3 buckets. If an attacker has acces...

Scrapy allows redirect following in protocols other than HTTP

Impact Scrapy was following redirects regardless of the URL protocol, so redirects were working for data://, file://, ftp://, s3://, and any other scheme defined in the DOWNLOADHANDLERS setting. However, HTTP redirects should only work between URLs that use the http:// or https:// schemes. A...

Scrapy's redirects ignoring scheme-specific proxy settings

Impact When using system proxy settings, which are scheme-specific i.e. specific to http:// or https:// URLs, Scrapy was not accounting for scheme changes during redirects. For example, an HTTP request would use the proxy configured for HTTP and, when redirected to an HTTPS URL, the new HTTPS...

Scrapy leaks the authorization header on same-domain but cross-origin redirects

Impact Since version 2.11.1, Scrapy drops the Authorization header when a request is redirected to a different domain. However, it keeps the header if the domain remains the same but the scheme http/https or the port change, all scenarios where the header should also be dropped. In the context of...
