An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-4171 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- calibreweb (PyPI): affected all versions; fixed in 0.6.15\n- calibreweb (PyPI): affected all versions; fixed in 0.6.15\n- calibreweb (PyPI): affected all versions; fixed in 0.6.15\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2021-4171/ (Markdown: https://insights.sbomify.com/CVE-2021-4171/index.md)","id":"CVE-2021-4171","markdown":"https://insights.sbomify.com/CVE-2021-4171/index.md","name":"CVE-2021-4171","record":{"aliases":["GHSA-xp7p-3gx7-j6wx","PYSEC-2026-307"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["other"],"network_reachable":"yes","non_default_config":false,"product_category":"Calibre Web","requires_auth":"high_privilege","summary":"Business logic errors in Calibre Web allow attackers to bypass intended application workflows, requiring users to update the software.","user_interaction":"not_required","vuln_class":"business_logic"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"@huntrdev","cpe":[{"product":"calibre-web","vendor":"janeczku"}],"cvss":{"score":7.7,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:N/AC:H/PR:H/UI:N/S:C/C:N/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-840","name":null}],"description":"calibre-web is vulnerable to Business Logic Errors","ecosystems":["PyPI"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Business Logic Errors in janeczku/calibre-web","id":"CVE-2021-4171","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":null,"products":[],"type":"business_logic","year":"2021"},"n_packages":3,"n_references":2,"next":{"headline":"Cross-site Scripting (XSS) - Stored in star7th/showdoc","id":"CVE-2021-4172"},"packages":[{"ecosystem":"PyPI","fixed":["0.6.15"],"introduced":["0"],"last_affected":[],"package":"calibreweb","purl":null,"source":"GHSA-xp7p-3gx7-j6wx"},{"ecosystem":"PyPI","fixed":["0.6.15"],"introduced":["0"],"last_affected":[],"package":"calibreweb","purl":"pkg:pypi/calibreweb","source":"GHSA-xp7p-3gx7-j6wx"},{"ecosystem":"PyPI","fixed":["0.6.15"],"introduced":["0"],"last_affected":[],"package":"calibreweb","purl":"pkg:pypi/calibreweb","source":"PYSEC-2026-307"}],"prev":{"headline":"Cross-site Scripting (XSS) - Stored in janeczku/calibre-web","id":"CVE-2021-4170"},"products":["janeczku/calibre-web"],"published":"2022-01-17","related":[{"cvss_score":9.8,"headline":"SQL injection in calibreweb","id":"CVE-2022-30765","kev_date_added":null,"published":"2022-05-16"},{"cvss_score":9.8,"headline":"Hardcoded credentials in n/a","id":"CVE-2020-12627","kev_date_added":null,"published":"2020-05-04"},{"cvss_score":9.3,"headline":"Server-Side Request Forgery (SSRF) in janeczku/calibre-web","id":"CVE-2022-0990","kev_date_added":null,"published":"2022-04-04"},{"cvss_score":9.1,"headline":"Server-Side Request Forgery (SSRF) in janeczku/calibre-web","id":"CVE-2022-0767","kev_date_added":null,"published":"2022-03-07"},{"cvss_score":9,"headline":"Server-Side Request Forgery (SSRF) in janeczku/calibre-web","id":"CVE-2022-0939","kev_date_added":null,"published":"2022-04-04"},{"cvss_score":8.8,"headline":"Calibre-web - Admin Account Takeover via Cross-Site Request Forgery (CSRF)","id":"CVE-2021-25965","kev_date_added":null,"published":"2021-11-16"},{"cvss_score":8.5,"headline":"Cross-site Scripting (XSS) - Reflected in janeczku/calibre-web","id":"CVE-2022-0352","kev_date_added":null,"published":"2022-01-28"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"PyPA Advisory Database","prefix":"PYSEC"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["janeczku"]},"summary":"Business logic errors in Calibre Web allow attackers to bypass intended application workflows, requiring users to update the software.","url":"https://insights.sbomify.com/CVE-2021-4171/"}
