This link is maintained to preserve external references.\n\n## Original Description\nIn 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 information disclosure to unauthorized actors. The flaw is located in the _build_redirect_request function of the redirect middleware.", "references": [ { "reference_url":

"summary": "Scrapy authorization header leakage on cross-domain redirect\n### Impact\n\nWhen you send a request with the `Authorization` header to one domain, and the response asks to redirect to a different domain, Scrapy’s built-in redirect middleware creates a follow-up redirect request that keeps the original `Authorization` header, leaking its content to that second domain.\n\nThe [right behavior](https://fetch.spec.whatwg.org/#ref-for-cors-non-wildcard-request-header-name) would be to drop the `Authorization` header instead, in this scenario.\n\n### Patches\n\nUpgrade to Scrapy 2.11.1.\n\nIf you are using Scrapy 1.8 or a lower version, and upgrading to Scrapy 2.11.1 is not an option, you may upgrade to Scrapy 1.8.4 instead.\n\n### Workarounds\n\nIf you cannot upgrade, make sure that you are not using the `Authentication` header, either directly or through some third-party plugin.\n\nIf you need to use that header in some requests, add `\"dont_redirect\": True` to the `request.meta` dictionary of those requests to disable following redirects for them.\n\nIf you need to keep (same domain) redirect support on those requests, make sure you trust the target website not to redirect your requests to a different domain.\n\n### Acknowledgements\n\nThis security issue was reported by @ranjit-git [through

"VCID-eps3-2rkz-r3gf", "summary": "Scrapy decompression bomb vulnerability\n### Impact\n\nScrapy limits allowed response sizes by default through the [`DOWNLOAD_MAXSIZE`](https://docs.scrapy.org/en/latest/topics/settings.html#download-maxsize) and [`DOWNLOAD_WARNSIZE`](https://docs.scrapy.org/en/latest/topics/settings.html#download-warnsize) settings.\n\nHowever, those limits were only being enforced during the download of the raw, usually-compressed response bodies, and not during decompression, making Scrapy vulnerable to [decompression bombs](https://cwe.mitre.org/data/definitions/409.html).\n\nA malicious website being scraped could send a small response that, on decompression, could exhaust the memory available to the Scrapy process, potentially affecting any other process sharing that memory, and affecting disk usage in case of uncompressed response caching.\n\n### Patches\n\nUpgrade to Scrapy 2.11.1.\n\nIf you are using Scrapy 1.8 or a lower version, and upgrading to Scrapy 2.11.1 is not an option, you may upgrade to Scrapy 1.8.4 instead.\n\n### Workarounds\n\nThere is no easy workaround.\n\nDisabling HTTP decompression altogether is impractical, as HTTP compression is a rather common practice.\n\nHowever, it is technically possible to manually backport the 2.11.1 or 1.8.4 fix, replacing the corresponding components of an unpatched version of Scrapy with patched versions copied into your own code.\n\n### Acknowledgements\n\nThis security issue was reported by @dmandefy [through

credentials to another\n### Impact\n\nWhen the [built-in HTTP proxy downloader middleware](https://docs.scrapy.org/en/2.6/topics/downloader-middleware.html#module-scrapy.downloadermiddlewares.httpproxy) processes a request with `proxy` metadata, and that `proxy` metadata includes proxy credentials, the built-in HTTP proxy downloader middleware sets the `Proxy-Authentication` header, but only if that header is not already set.\n\nThere are third-party proxy-rotation downloader middlewares that set different `proxy` metadata every time they process a request.\n\nBecause of request retries and redirects, the same request can be processed by downloader middlewares more than once, including both the built-in HTTP proxy downloader middleware and any third-party proxy-rotation downloader middleware.\n\nThese third-party proxy-rotation downloader middlewares could change the `proxy` metadata of a request to a new value, but fail to remove the `Proxy-Authentication` header from the previous value of the `proxy` metadata, causing the credentials of one proxy to be leaked to a different proxy.\n\nIf you rotate proxies from different proxy providers, and any of those proxies requires credentials, you are affected, unless you are handling proxy rotation as described under **Workarounds** below. If you use a third-party downloader middleware for proxy rotation, the same applies to that downloader middleware, and installing a patched version of Scrapy may not be enough; patching that downloader middlware may be necessary as well.\n\n### Patches\n\nUpgrade to Scrapy 2.6.2.\n\nIf you are using Scrapy 1.8 or a lower version, and upgrading to Scrapy 2.6.2 is not an option, you may upgrade to Scrapy 1.8.3 instead.\n\n### Workarounds\n\nIf you cannot upgrade, make sure that any code that changes the value of the `proxy` request meta also removes the `Proxy-Authorization` header from the request if present.\n\n### For more information\n\nIf you have any questions or comments about this advisory:\n* [Open an issue](https://github.com/scrapy/scrapy/issues)\n* [Email us](mailto:opensource@zyte.com)", "references": [ { "reference_url": "https://github.com/scrapy/scrapy", "reference_id": "", "reference_type": "", "scores": [ { "value": "MODERATE", "scoring_system": "generic_textual", "scoring_elements": "" } ], "url": "https://github.com/scrapy/scrapy" }, { "reference_url": "https://github.com/scrapy/scrapy/commit/af7dd16d8ded3e6cb2946603688f4f4a5212e80f", "reference_id": "", "reference_type": "", "scores": [ { "value": "MODERATE", "scoring_system": "generic_textual", "scoring_elements": "" } ], "url": "https://github.com/scrapy/scrapy/commit/af7dd16d8ded3e6cb2946603688f4f4a5212e80f" }, { "reference_url": "https://github.com/scrapy/scrapy/security/advisories/GHSA-9x8m-2xpf-crp3", "reference_id": "", "reference_type": "", "scores": [ { "value": "MODERATE", "scoring_system": "cvssv3.1_qr", "scoring_elements": "" }, { "value": "MODERATE", "scoring_system": "generic_textual", "scoring_elements": "" } ], "url": "https://github.com/scrapy/scrapy/security/advisories/GHSA-9x8m-2xpf-crp3" }, { "reference_url": "https://github.com/advisories/GHSA-9x8m-2xpf-crp3", "reference_id": "GHSA-9x8m-2xpf-crp3", "reference_type": "", "scores": [ { "value": "MODERATE", "scoring_system": "cvssv3.1_qr", "scoring_elements": "" } ], "url": "https://github.com/advisories/GHSA-9x8m-2xpf-crp3" } ], "fixed_packages": [ { "url": "http://public2.vulnerablecode.io/api/packages/40518?format=api", "purl": "pkg:pypi/scrapy@1.8.3", "is_vulnerable": true, "affected_by_vulnerabilities": [ { "vulnerability": "VCID-2zwa-9vsz-uqft" }, { "vulnerability": "VCID-42hv-czj8-hybb" }, { "vulnerability": "VCID-atnw-pnvj-zkhp" }, { "vulnerability": "VCID-eps3-2rkz-r3gf" }, { "vulnerability": "VCID-jrh5-kjau-xkar" }, { "vulnerability": "VCID-n6z2-awrh-7kbg" }, { "vulnerability": "VCID-nhpt-g7eq-vubm" }, { "vulnerability": "VCID-rbs9-h2ay-qybj" }, { "vulnerability": "VCID-spj3-t26x-aba3" }, { "vulnerability": "VCID-u3b1-bupn-hkdv" }, { "vulnerability": "VCID-uwag-f4xk-yqaw" }, { "vulnerability": "VCID-zt2j-kfrr-7yct" } ], "resource_url": "http://public2.vulnerablecode.io/packages/pkg:pypi/scrapy@1.8.3" }, { "url": "http://public2.vulnerablecode.io/api/packages/40520?format=api", "purl": "pkg:pypi/scrapy@2.6.2", "is_vulnerable": true, "affected_by_vulnerabilities": [ { "vulnerability": "VCID-2zwa-9vsz-uqft" }, { "vulnerability": "VCID-42hv-czj8-hybb" }, { "vulnerability": "VCID-atnw-pnvj-zkhp" }, { "vulnerability": "VCID-eps3-2rkz-r3gf" }, { "vulnerability": "VCID-n6z2-awrh-7kbg" }, { "vulnerability": "VCID-nhpt-g7eq-vubm" }, { "vulnerability": "VCID-rbs9-h2ay-qybj" }, { "vulnerability": "VCID-spj3-t26x-aba3" }, { "vulnerability": "VCID-u3b1-bupn-hkdv" }, { "vulnerability": "VCID-uwag-f4xk-yqaw" }, { "vulnerability": "VCID-zt2j-kfrr-7yct" } ], "resource_url": "http://public2.vulnerablecode.io/packages/pkg:pypi/scrapy@2.6.2" } ], "aliases": [ "GHSA-9x8m-2xpf-crp3", "GMS-2022-3357" ], "risk_score": 3.1, "exploitability": "0.5", "weighted_severity": "6.2", "resource_url": "http://public2.vulnerablecode.io/vulnerabilities/VCID-meu9-utc1-43bf" }, { "url": "http://public2.vulnerablecode.io/api/vulnerabilities/36795?format=api", "vulnerability_id": "VCID-n6z2-awrh-7kbg", "summary": "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.

A spider that always outputs the entire contents of a response would be completely vulnerable, while a spider that extracted only fragments from the response could significantly limit vulnerable data.", "references": [ { "reference_url": "https://github.com/scrapy/scrapy", "reference_id": "", "reference_type": "", "scores": [ { "value": "6.5", "scoring_system": "cvssv3.1", "scoring_elements": "CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N" }, { "value": "MODERATE", "scoring_system": "generic_textual", "scoring_elements": "" } ], "url": "https://github.com/scrapy/scrapy" }, { "reference_url": "https://github.com/scrapy/scrapy/commit/36287cb665ab4b0c65fd53181c9a0ef04990ada6", "reference_id": "", "reference_type": "", "scores": [ { "value": "6.5", "scoring_system": "cvssv3.1", "scoring_elements": "CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N" }, { "value": "MODERATE", "scoring_system": "generic_textual", "scoring_elements": "" } ], "url": "https://github.com/scrapy/scrapy/commit/36287cb665ab4b0c65fd53181c9a0ef04990ada6" }, { "reference_url": "https://github.com/scrapy/scrapy/issues/457", "reference_id": "", "reference_type": "", "scores": [ { "value": "6.5", "scoring_system": "cvssv3.1", "scoring_elements": "CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N" }, { "value": "MODERATE", "scoring_system": "generic_textual", "scoring_elements": "" } ], "url": "https://github.com/scrapy/scrapy/issues/457" }, { "reference_url": "https://github.com/advisories/GHSA-23j4-mw76-5v7h", "reference_id": "GHSA-23j4-mw76-5v7h", "reference_type": "", "scores": [ { "value": "MODERATE", "scoring_system": "cvssv3.1_qr", "scoring_elements": "" } ], "url": "https://github.com/advisories/GHSA-23j4-mw76-5v7h" }, { "reference_url": "https://github.com/scrapy/scrapy/security/advisories/GHSA-23j4-mw76-5v7h", "reference_id": "GHSA-23j4-mw76-5v7h", "reference_type": "", "scores": [ { "value": "6.5", "scoring_system": "cvssv3.1", "scoring_elements": "CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N" }, { "value": "MODERATE", "scoring_system": "cvssv3.1_qr", "scoring_elements": "" }, { "value": "MODERATE", "scoring_system": "generic_textual", "scoring_elements": "" } ], "url": "https://github.com/scrapy/scrapy/security/advisories/GHSA-23j4-mw76-5v7h" } ], "fixed_packages": [ { "url": "http://public2.vulnerablecode.io/api/packages/41041?format=api", "purl": "pkg:pypi/scrapy@2.11.2", "is_vulnerable": true, "affected_by_vulnerabilities": [ { "vulnerability": "VCID-u3b1-bupn-hkdv" }, { "vulnerability": "VCID-uwag-f4xk-yqaw" } ], "resource_url": "http://public2.vulnerablecode.io/packages/pkg:pypi/scrapy@2.11.2" } ], "aliases": [ "GHSA-23j4-mw76-5v7h" ], "risk_score": null, "exploitability": null, "weighted_severity": null, "resource_url": "http://public2.vulnerablecode.io/vulnerabilities/VCID-zt2j-kfrr-7yct" } ], "fixing_vulnerabilities": [], "risk_score": "4.0", "resource_url": "http://public2.vulnerablecode.io/packages/pkg:pypi/scrapy@0.20.2" }
