An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-80231 exists.\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-2026-80231/ (Markdown: https://insights.sbomify.com/CVE-2026-80231/index.md)","id":"CVE-2026-80231","markdown":"https://insights.sbomify.com/CVE-2026-80231/index.md","name":"CVE-2026-80231","record":{"aliases":["ALPINE-CVE-2026-80231","AZL-99758","AZL-99774","AZL-99807","AZL-99831","AZL-99855","AZL-99876","BELL-CVE-2026-80231","CURL-CVE-2026-80231","GHSA-r8j3-cwj5-4j73","MINI-c23j-q8hr-29p8","MINI-v3rv-q8cj-2pm6","ROOT-OS-ALPINE-315-CVE-2026-80231","ROOT-OS-ALPINE-320-CVE-2026-80231","ROOT-OS-ALPINE-321-CVE-2026-80231","ROOT-OS-ALPINE-322-CVE-2026-80231"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"libcurl HTTP library","requires_auth":"none","summary":"Attackers can bypass native CA store security settings by reusing existing HTTPS connections, potentially allowing untrusted certificate validation.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"curl","cpe":[{"product":"curl","vendor":"haxx"}],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-488","name":"Exposure of Data Element to Wrong Session"}],"description":"A flaw in libcurl makes it wrongly reuse an existing HTTPS connection setup\nfor a given hostname even when using a different Native CA Store setting\n(`CURLSSLOPT_NATIVE_CA`) than when the connection was created.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"native CA store conn reuse","id":"CVE-2026-80231","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"haxx:curl","products":["haxx:curl"],"type":"security_feature_bypass","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"CAYIN Technology｜CAYIN CMS-WS/CMS-SE/SMP - Arbitrary File Upload","id":"CVE-2026-80233"},"packages":[],"prev":{"headline":"OpenSSL pinning bypass","id":"CVE-2026-80230"},"products":["curl"],"published":"2026-09-06","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":"yes","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-15","vendors":["curl"]},"summary":"Attackers can bypass native CA store security settings by reusing existing HTTPS connections, potentially allowing untrusted certificate validation.","url":"https://insights.sbomify.com/CVE-2026-80231/"}
