An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-28724 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- werkzeug (PyPI): affected all versions; fixed in 0.11.6\n- werkzeug (PyPI): affected all versions; fixed in 0.11.6\n- werkzeug (PyPI): affected all versions; fixed in 0.11.6\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-2020-28724/ (Markdown: https://insights.sbomify.com/CVE-2020-28724/index.md)","id":"CVE-2020-28724","markdown":"https://insights.sbomify.com/CVE-2020-28724/index.md","name":"CVE-2020-28724","record":{"aliases":["DEBIAN-CVE-2020-28724","GHSA-3p3h-qghp-hvh2","PYSEC-2020-157","UBUNTU-CVE-2020-28724"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Python web library","requires_auth":"none","summary":"An attacker can redirect users to malicious sites via a double slash in the URL, affecting applications using the Werkzeug library.","user_interaction":"required","vuln_class":"open_redirect"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"werkzeug","vendor":"palletsprojects"}],"cvss":{"score":6.1,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-601","name":"URL Redirection to Untrusted Site"}],"description":"Open redirect vulnerability in werkzeug before 0.11.6 via a double slash in the URL.","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":"Open Redirect in werkzeug","id":"CVE-2020-28724","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":null,"products":[],"type":"open_redirect","year":"2020"},"n_packages":3,"n_references":3,"next":{"headline":"Open redirect in n/a","id":"CVE-2020-28726"},"packages":[{"ecosystem":"PyPI","fixed":["0.11.6"],"introduced":["0"],"last_affected":[],"package":"werkzeug","purl":null,"source":"GHSA-3p3h-qghp-hvh2"},{"ecosystem":"PyPI","fixed":["0.11.6"],"introduced":["0"],"last_affected":[],"package":"werkzeug","purl":"pkg:pypi/werkzeug","source":"GHSA-3p3h-qghp-hvh2"},{"ecosystem":"PyPI","fixed":["0.11.6"],"introduced":["0"],"last_affected":[],"package":"werkzeug","purl":"pkg:pypi/werkzeug","source":"PYSEC-2020-157"}],"prev":{"headline":"Denial of service in n/a","id":"CVE-2020-28723"},"products":["n/a"],"published":"2020-11-18","related":[{"cvss_score":9.8,"headline":"Other in n/a","id":"CVE-2022-29361","kev_date_added":null,"published":"2022-05-24"},{"cvss_score":8,"headline":"Werkzeug DoS: High resource usage when parsing multipart/form-data containing a large part with CR/LF character at the beginning","id":"CVE-2023-46136","kev_date_added":null,"published":"2023-10-24"},{"cvss_score":7.5,"headline":"Werkzeug may allow high resource usage when parsing multipart form data with many fields","id":"CVE-2023-25577","kev_date_added":null,"published":"2023-02-14"},{"cvss_score":7.5,"headline":"Pallets Werkzeug vulnerable to Path Traversal","id":"CVE-2019-14322","kev_date_added":null,"published":"2019-07-28"},{"cvss_score":6.3,"headline":"Werkzeug safe_join() allows Windows special device names","id":"CVE-2026-27199","kev_date_added":null,"published":"2026-02-21"},{"cvss_score":6.3,"headline":"Werkzeug safe_join() allows Windows special device names with compound extensions","id":"CVE-2026-21860","kev_date_added":null,"published":"2026-01-08"},{"cvss_score":6.3,"headline":"Werkzeug safe_join() allows Windows special device names","id":"CVE-2025-66221","kev_date_added":null,"published":"2025-11-29"}],"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":"2024-08-04","vendors":["n/a"]},"summary":"An attacker can redirect users to malicious sites via a double slash in the URL, affecting applications using the Werkzeug library.","url":"https://insights.sbomify.com/CVE-2020-28724/"}
