Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-6429 in the wild and no public exploit code.\n\nAffected product: Haxx Curl. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-6429/ (Markdown: https://insights.sbomify.com/CVE-2026-6429/index.md)","id":"CVE-2026-6429","markdown":"https://insights.sbomify.com/CVE-2026-6429/index.md","name":"CVE-2026-6429","record":{"aliases":["ALPINE-CVE-2026-6429","AZL-86661","AZL-86688","BELL-CVE-2026-6429","CURL-CVE-2026-6429","DEBIAN-CVE-2026-6429","ECHO-2ec8-1a62-f90d","GHSA-2pvc-5qw9-h3ph","JLSEC-2026-1208","MINI-6hqm-ww8p-h58r","MINI-fjgf-3rf4-f8px","ROOT-OS-DEBIAN-11-CVE-2026-6429","ROOT-OS-DEBIAN-12-CVE-2026-6429","UBUNTU-CVE-2026-6429"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"curl library","requires_auth":"low_privilege","summary":"An attacker can steal netrc credentials from the first host when libcurl follows HTTP redirects to a different host.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"curl","cpe":[{"product":"curl","vendor":"haxx"}],"cvss":{"score":5.3,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"When asked to both use a `.netrc` file for credentials and to follow HTTP\nredirects, libcurl could leak the password used for the first host to the\nfollowed-to host under certain circumstances.","ecosystems":[],"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":"netrc credential leak with reused proxy connection","id":"CVE-2026-6429","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"haxx:curl","products":["haxx:curl"],"type":"information_disclosure","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"User Profile Builder \u003c= 3.15.7 - Unauthenticated Stored Cross-Site Scripting via 'Biographical Info' Meta Field","id":"CVE-2026-6431"},"packages":[],"prev":{"headline":"Koha SQL Injection in reports/catalogue_out.pl via Filter URL Parameter","id":"CVE-2026-6428"},"products":["curl"],"published":"2026-05-13","related":[{"cvss_score":9.8,"headline":"Negotiate ambient user conn reuse","id":"CVE-2026-19931","kev_date_added":null,"published":"2026-09-06"},{"cvss_score":9.8,"headline":"HTTP/2 stream-dependency tree UAF","id":"CVE-2026-10536","kev_date_added":null,"published":"2026-07-03"},{"cvss_score":9.8,"headline":"cross-origin Digest auth state leak","id":"CVE-2026-11856","kev_date_added":null,"published":"2026-07-03"},{"cvss_score":9.8,"headline":"SASL double-free","id":"CVE-2026-8925","kev_date_added":null,"published":"2026-07-03"},{"cvss_score":9.8,"headline":"stale proxy password leak","id":"CVE-2026-9079","kev_date_added":null,"published":"2026-07-03"},{"cvss_score":9.8,"headline":"Code injection in curl","id":"CVE-2016-4606","kev_date_added":null,"published":"2020-02-21"},{"cvss_score":9.8,"headline":"Information disclosure in n/a","id":"CVE-2016-9953","kev_date_added":null,"published":"2018-03-12"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2026-09-15","vendors":["curl"]},"summary":"An attacker can steal netrc credentials from the first host when libcurl follows HTTP redirects to a different host.","url":"https://insights.sbomify.com/CVE-2026-6429/"}
