For example:\n\n```python\nRequest(\n url,\n meta={\n \"referrer_policy\": \"scrapy.spidermiddlewares.referer.DefaultReferrerPolicy\",\n },\n)\n```\n\nInstead of editing requests individually, you can:\n\n- implement a custom [spider middleware](https://docs.scrapy.org/en/latest/topics/spider-middleware.html) that runs before the built-in referrer policy middleware and sets the `referrer_policy` meta key; or\n- set the meta key in start requests and use the [scrapy-sticky-meta-params](https://github.com/heylouiz/scrapy-sticky-meta-params) plugin to propagate it to follow-up requests.\n\nIf you want to continue respecting legitimate `Referrer-Policy` headers while protecting against malicious ones, disable the built-in referrer policy middleware by setting it to `None` in [`SPIDER_MIDDLEWARES`](https://docs.scrapy.org/en/latest/topics/settings.html#std-setting-SPIDER_MIDDLEWARES) and replace it with the fixed implementation from Scrapy 2.14.2.\n\nIf the Scrapy 2.14.2 implementation is incompatible with your project (for example, because your Scrapy version is older), copy the corresponding middleware from your Scrapy version, apply the same patch, and use that as a replacement.", "references": [ { "reference_url": "https://github.com/scrapy/scrapy", "reference_id": "", "reference_type": "", "scores": [ { "value": "7.5", "scoring_system": "cvssv3.1",

"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

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

Impact\n\nScrapy was following redirects regardless of the URL protocol, so redirects were working for `data://`, `file://`, `ftp://`, `s3://`, and any other scheme defined in the `DOWNLOAD_HANDLERS` setting.\n\nHowever, HTTP redirects should only work between URLs that use the `http://` or `https://` schemes.\n\nA malicious actor, given write access to the start requests (e.g. ability to define `start_urls`) of a spider and read access to the spider output, could exploit this vulnerability to:\n- Redirect to any local file using the `file://` scheme to read its contents.\n- Redirect to an `ftp://` URL of a malicious FTP server to obtain the FTP username and password configured in the spider or project.\n- Redirect to any `s3://` URL to read its content using the S3 credentials configured in the spider or project.\n\nFor `file://` and `s3://`, how the spider implements its parsing of input data into an output item determines what data would be vulnerable. 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.\n\n### Patches\n\nUpgrade to Scrapy 2.11.2.\n\n### Workarounds\n\nReplace the built-in retry middlewares (`RedirectMiddleware` and `MetaRefreshMiddleware`) with custom ones that implement the fix from Scrapy 2.11.2, and verify that they work as intended.\n\n### References\n\nThis security issue was reported by @mvsantos at https://github.com/scrapy/scrapy/issues/457.", "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/scrapy/scrapy/security/advisories/GHSA-23j4-mw76-5v7h", "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": "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" }, { "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" } ], "fixed_packages": [ { "url": "http://public2.vulnerablecode.io/api/packages/46023?format=api", "purl": "pkg:pypi/scrapy@2.11.2", "is_vulnerable": true, "affected_by_vulnerabilities": [ { "vulnerability": "VCID-1k4b-pr5k-s7e5" }, { "vulnerability": "VCID-dc1m-rt7j-w3af" } ], "resource_url": "http://public2.vulnerablecode.io/packages/pkg:pypi/scrapy@2.11.2" } ], "aliases": [ "GHSA-23j4-mw76-5v7h" ], "risk_score": 3.1, "exploitability": "0.5", "weighted_severity": "6.2", "resource_url": "http://public2.vulnerablecode.io/vulnerabilities/VCID-nekz-z7zw-mfgz" }, { "url": "http://public2.vulnerablecode.io/api/vulnerabilities/19159?format=api", "vulnerability_id": "VCID-t5cn-a543-nyag", "summary": "Duplicate Advisory: Scrapy leaks the authorization header on same-domain but cross-origin redirects\n## Duplicate Advisory\nThis advisory has been withdrawn because it is a duplicate of GHSA-4qqq-9vqf-3h3f.

Same the other way around.\n\nIf you have different proxy configurations for HTTP and HTTPS in your system for security reasons (e.g., maybe you don’t want one of your proxy providers to be aware of the URLs that you visit with the other one), this would be a security issue.\n\n### Patches\n\nUpgrade to Scrapy 2.11.2.\n\n### Workarounds\n\nReplace the built-in retry middlewares (`RedirectMiddleware` and `MetaRefreshMiddleware`) and the `HttpProxyMiddleware` middleware with custom ones that implement the fix from Scrapy 2.11.2, and verify that they work as intended.\n\n### References\n\nThis security issue was reported by @redapple at https://github.com/scrapy/scrapy/issues/767.", "references": [ { "reference_url": "https://github.com/scrapy/scrapy", "reference_id": "", "reference_type": "", "scores": [ { "value": "4.3", "scoring_system": "cvssv3.1", "scoring_elements": "CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/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/1d0502f25bbe55a22899af915623fda1aaeb9dd8", "reference_id": "", "reference_type": "", "scores": [ { "value": "4.3", "scoring_system": "cvssv3.1", "scoring_elements": "CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N" }, { "value": "MODERATE", "scoring_system": "generic_textual", "scoring_elements": "" } ], "url": "https://github.com/scrapy/scrapy/commit/1d0502f25bbe55a22899af915623fda1aaeb9dd8" }, { "reference_url": "https://github.com/scrapy/scrapy/issues/767", "reference_id": "", "reference_type": "", "scores": [ { "value": "4.3", "scoring_system": "cvssv3.1", "scoring_elements": "CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N" }, { "value": "MODERATE", "scoring_system": "generic_textual", "scoring_elements": "" } ], "url": "https://github.com/scrapy/scrapy/issues/767" }, { "reference_url": "https://github.com/scrapy/scrapy/security/advisories/GHSA-jm3v-qxmh-hxwv", "reference_id": "", "reference_type": "", "scores": [ { "value": "4.3", "scoring_system": "cvssv3.1", "scoring_elements": "CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/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-jm3v-qxmh-hxwv" }, { "reference_url": "https://github.com/advisories/GHSA-jm3v-qxmh-hxwv", "reference_id": "GHSA-jm3v-qxmh-hxwv", "reference_type": "", "scores": [ { "value": "MODERATE", "scoring_system": "cvssv3.1_qr", "scoring_elements": "" } ], "url": "https://github.com/advisories/GHSA-jm3v-qxmh-hxwv" } ], "fixed_packages": [ { "url": "http://public2.vulnerablecode.io/api/packages/46023?format=api", "purl": "pkg:pypi/scrapy@2.11.2", "is_vulnerable": true, "affected_by_vulnerabilities": [ { "vulnerability": "VCID-1k4b-pr5k-s7e5" }, { "vulnerability": "VCID-dc1m-rt7j-w3af" } ], "resource_url": "http://public2.vulnerablecode.io/packages/pkg:pypi/scrapy@2.11.2" } ], "aliases": [ "GHSA-jm3v-qxmh-hxwv" ], "risk_score": 3.1, "exploitability": "0.5", "weighted_severity": "6.2", "resource_url": "http://public2.vulnerablecode.io/vulnerabilities/VCID-veaw-n6vt-zfgu" } ], "fixing_vulnerabilities": [], "risk_score": "4.0", "resource_url": "http://public2.vulnerablecode.io/packages/pkg:pypi/scrapy@2.10.0" }
