{"url":"http://public2.vulnerablecode.io/api/vulnerabilities/35885?format=json","vulnerability_id":"VCID-4dpn-nt6h-6uhe","summary":"Scrapy-splash is a library which provides Scrapy and JavaScript integration. In affected versions users who use [`HttpAuthMiddleware`](http://doc.scrapy.org/en/latest/topics/downloader-middleware.html#module-scrapy.downloadermiddlewares.httpauth) (i.e. the `http_user` and `http_pass` spider attributes) for Splash authentication will have any non-Splash request expose your credentials to the request target. This includes `robots.txt` requests sent by Scrapy when the `ROBOTSTXT_OBEY` setting is set to `True`. Upgrade to scrapy-splash 0.8.0 and use the new `SPLASH_USER` and `SPLASH_PASS` settings instead to set your Splash authentication credentials safely. If you cannot upgrade, set your Splash request credentials on a per-request basis, [using the `splash_headers` request parameter](https://github.com/scrapy-plugins/scrapy-splash/tree/0.8.x#http-basic-auth), instead of defining them globally using the [`HttpAuthMiddleware`](http://doc.scrapy.org/en/latest/topics/downloader-middleware.html#module-scrapy.downloadermiddlewares.httpauth). Alternatively, make sure all your requests go through Splash. That includes disabling the [robots.txt middleware](https://docs.scrapy.org/en/latest/topics/downloader-middleware.html#topics-dlmw-robots).","aliases":[{"alias":"CVE-2021-41124"},{"alias":"GHSA-823f-cwm9-4g74"},{"alias":"PYSEC-2021-364"}],"fixed_packages":[{"url":"http://public2.vulnerablecode.io/api/packages/23915?format=json","purl":"pkg:pypi/scrapy-splash@0.8.0","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/scrapy-splash@0.8.0"}],"affected_packages":[{"url":"http://public2.vulnerablecode.io/api/packages/23906?format=json","purl":"pkg:pypi/scrapy-splash@0.2","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-4dpn-nt6h-6uhe"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/scrapy-splash@0.2"},{"url":"http://public2.vulnerablecode.io/api/packages/23907?format=json","purl":"pkg:pypi/scrapy-splash@0.3","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-4dpn-nt6h-6uhe"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/scrapy-splash@0.3"},{"url":"http://public2.vulnerablecode.io/api/packages/23908?format=json","purl":"pkg:pypi/scrapy-splash@0.4","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-4dpn-nt6h-6uhe"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/scrapy-splash@0.4"},{"url":"http://public2.vulnerablecode.io/api/packages/23909?format=json","purl":"pkg:pypi/scrapy-splash@0.5","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-4dpn-nt6h-6uhe"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/scrapy-splash@0.5"},{"url":"http://public2.vulnerablecode.io/api/packages/23910?format=json","purl":"pkg:pypi/scrapy-splash@0.6","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-4dpn-nt6h-6uhe"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/scrapy-splash@0.6"},{"url":"http://public2.vulnerablecode.io/api/packages/23911?format=json","purl":"pkg:pypi/scrapy-splash@0.6.1","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-4dpn-nt6h-6uhe"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/scrapy-splash@0.6.1"},{"url":"http://public2.vulnerablecode.io/api/packages/23912?format=json","purl":"pkg:pypi/scrapy-splash@0.7","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-4dpn-nt6h-6uhe"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/scrapy-splash@0.7"},{"url":"http://public2.vulnerablecode.io/api/packages/23913?format=json","purl":"pkg:pypi/scrapy-splash@0.7.1","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-4dpn-nt6h-6uhe"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/scrapy-splash@0.7.1"},{"url":"http://public2.vulnerablecode.io/api/packages/23914?format=json","purl":"pkg:pypi/scrapy-splash@0.7.2","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-4dpn-nt6h-6uhe"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/scrapy-splash@0.7.2"}],"references":[{"reference_url":"https://api.first.org/data/v1/epss?cve=CVE-2021-41124","reference_id":"","reference_type":"","scores":[{"value":"0.00284","scoring_system":"epss","scoring_elements":"0.52062","published_at":"2026-06-05T12:55:00Z"},{"value":"0.00284","scoring_system":"epss","scoring_elements":"0.52038","published_at":"2026-06-09T12:55:00Z"},{"value":"0.00284","scoring_system":"epss","scoring_elements":"0.52019","published_at":"2026-06-08T12:55:00Z"},{"value":"0.00284","scoring_system":"epss","scoring_elements":"0.5205","published_at":"2026-06-07T12:55:00Z"},{"value":"0.00284","scoring_system":"epss","scoring_elements":"0.52001","published_at":"2026-06-04T12:55:00Z"},{"value":"0.00284","scoring_system":"epss","scoring_elements":"0.52071","published_at":"2026-06-06T12:55:00Z"}],"url":"https://api.first.org/data/v1/epss?cve=CVE-2021-41124"},{"reference_url":"https://github.com/pypa/advisory-database/tree/main/vulns/scrapy-splash/PYSEC-2021-364.yaml","reference_id":"","reference_type":"","scores":[{"value":"7.4","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:N/A:N"},{"value":"8.2","scoring_system":"cvssv4","scoring_elements":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:N/VA:N/SC:H/SI:N/SA:N"},{"value":"HIGH","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://github.com/pypa/advisory-database/tree/main/vulns/scrapy-splash/PYSEC-2021-364.yaml"},{"reference_url":"https://github.com/scrapy-plugins/scrapy-splash","reference_id":"","reference_type":"","scores":[{"value":"7.4","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:N/A:N"},{"value":"8.2","scoring_system":"cvssv4","scoring_elements":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:N/VA:N/SC:H/SI:N/SA:N"},{"value":"HIGH","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://github.com/sc
