An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2023-45143 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- undici (npm): affected all versions; fixed in 5.26.2\n- undici (npm): affected all versions; fixed in 5.26.2\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-2023-45143/ (Markdown: https://insights.sbomify.com/CVE-2023-45143/index.md)","id":"CVE-2023-45143","markdown":"https://insights.sbomify.com/CVE-2023-45143/index.md","name":"CVE-2023-45143","record":{"aliases":["ALPINE-CVE-2023-45143","AZL-31338","CLEANSTART-2026-QW98383","CLEANSTART-2026-TM79261","CLEANSTART-2026-ZI83598","CLSA-2026-1775220180","DEBIAN-CVE-2023-45143","GHSA-wqq4-5wpv-mx2g","UBUNTU-CVE-2023-45143"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Node.js HTTP client","requires_auth":"high_privilege","summary":"Undici fails to clear Cookie headers on cross-origin redirects, potentially leaking sensitive cookies to third-party sites or attackers controlling redirect targets.","user_interaction":"required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"fedora","vendor":"fedoraproject"},{"product":"undici","vendor":"nodejs"}],"cvss":{"score":3.9,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:R/S:U/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"Undici is an HTTP/1.1 client written from scratch for Node.js. Prior to version 5.26.2, Undici already cleared Authorization headers on cross-origin redirects, but did not clear `Cookie` headers. By design, `cookie` headers are forbidden request headers, disallowing them to be set in RequestInit.headers in browser environments. Since undici handles headers more liberally than the spec, there was a disconnect from the assumptions the spec made, and undici's implementation of fetch. As such this may lead to accidental leakage of cookie to a third-party site or a malicious attacker who can control the redirection target (ie. an open redirector) to leak the cookie to the third party site. This was patched in version 5.26.2. There are no known workarounds.","ecosystems":["npm"],"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":"Undici's cookie header not cleared on cross-origin redirect in fetch","id":"CVE-2023-45143","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":"fedoraproject:fedora","products":["fedoraproject:fedora","nodejs:undici"],"type":"information_disclosure","year":"2023"},"n_packages":2,"n_references":11,"next":{"headline":"Remote code execution from login screen through unescaped URL parameter in OAuth Identity XWiki App","id":"CVE-2023-45144"},"packages":[{"ecosystem":"npm","fixed":["5.26.2"],"introduced":["0"],"last_affected":[],"package":"undici","purl":null,"source":"GHSA-wqq4-5wpv-mx2g"},{"ecosystem":"npm","fixed":["5.26.2"],"introduced":["0"],"last_affected":[],"package":"undici","purl":"pkg:npm/undici","source":"GHSA-wqq4-5wpv-mx2g"}],"prev":{"headline":"OpenTelemetry-Go Contrib has DoS vulnerability in otelhttp due to unbound cardinality metrics","id":"CVE-2023-45142"},"products":["undici"],"published":"2023-10-12","related":[{"cvss_score":9.8,"headline":"PHP-CGI OS Command Injection","id":"CVE-2024-4577","kev_date_added":"2024-06-12","published":"2024-06-09"},{"cvss_score":9.8,"headline":"Grafana Authentication Bypass","id":"CVE-2021-39226","kev_date_added":"2022-08-25","published":"2021-10-05"},{"cvss_score":9.8,"headline":"VMware ESXi and Horizon DaaS OpenSLP Heap-Based Buffer Overflow","id":"CVE-2019-5544","kev_date_added":"2021-11-03","published":"2019-12-06"},{"cvss_score":9.6,"headline":"Google Chromium V8 Type Confusion","id":"CVE-2024-4947","kev_date_added":"2024-05-20","published":"2024-05-15"},{"cvss_score":9.6,"headline":"Google Chromium Visuals Use-After-Free","id":"CVE-2024-4671","kev_date_added":"2024-05-13","published":"2024-05-09"},{"cvss_score":9.6,"headline":"Google Chromium Mojo Insufficient Data Validation","id":"CVE-2022-3075","kev_date_added":"2022-09-08","published":"2022-09-26"},{"cvss_score":9.6,"headline":"Google Chromium Indexed DB API Use-After-Free","id":"CVE-2021-30633","kev_date_added":"2021-11-03","published":"2021-10-08"}],"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":"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-02-13","vendors":["nodejs"]},"summary":"Undici fails to clear Cookie headers on cross-origin redirects, potentially leaking sensitive cookies to third-party sites or attackers controlling redirect targets.","url":"https://insights.sbomify.com/CVE-2023-45143/"}
