An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-3784 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-2026-3784/ (Markdown: https://insights.sbomify.com/CVE-2026-3784/index.md)","id":"CVE-2026-3784","markdown":"https://insights.sbomify.com/CVE-2026-3784/index.md","name":"CVE-2026-3784","record":{"aliases":["ALPINE-CVE-2026-3784","AZL-79679","BELL-CVE-2026-3784","CLSA-2026-1774273500","CLSA-2026-1774276586","CURL-CVE-2026-3784","DEBIAN-CVE-2026-3784","ECHO-f726-ae66-88e1","GHSA-5q3w-6p3j-mw6p","JLSEC-2026-438","MINI-hrrg-xpmx-8mjr","ROOT-OS-DEBIAN-11-CVE-2026-3784","ROOT-OS-DEBIAN-12-CVE-2026-3784","UBUNTU-CVE-2026-3784"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"curl library","requires_auth":"none","summary":"curl incorrectly reuses proxy connections with different credentials, allowing potential authentication bypass or credential leakage.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"curl","cpe":[{"product":"curl","vendor":"haxx"}],"cvss":{"score":6.5,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-305","name":"Authentication Bypass by Primary Weakness"}],"description":"curl would wrongly reuse an existing HTTP proxy connection doing CONNECT to a\nserver, even if the new request uses different credentials for the HTTP proxy.\nThe proper behavior is to create or use a separate connection.","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":"wrong proxy connection reuse with credentials","id":"CVE-2026-3784","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"haxx:curl","products":["haxx:curl"],"type":"auth_bypass","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"EasyCMS Request Parameter RbacnodeAction.class.php sql injection","id":"CVE-2026-3785"},"packages":[],"prev":{"headline":"token leak with redirect and netrc","id":"CVE-2026-3783"},"products":["curl"],"published":"2026-03-11","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":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-15","vendors":["curl"]},"summary":"curl incorrectly reuses proxy connections with different credentials, allowing potential authentication bypass or credential leakage.","url":"https://insights.sbomify.com/CVE-2026-3784/"}
