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-2026-3805 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-2026-3805/ (Markdown: https://insights.sbomify.com/CVE-2026-3805/index.md)","id":"CVE-2026-3805","markdown":"https://insights.sbomify.com/CVE-2026-3805/index.md","name":"CVE-2026-3805","record":{"aliases":["ALPINE-CVE-2026-3805","BELL-CVE-2026-3805","CURL-CVE-2026-3805","DEBIAN-CVE-2026-3805","ECHO-4deb-219d-e7eb","GHSA-2289-hhfc-p684","JLSEC-2026-439","MINI-gf7q-pwf6-rv36","ROOT-OS-ALPINE-320-CVE-2026-3805","ROOT-OS-ALPINE-321-CVE-2026-3805","ROOT-OS-ALPINE-322-CVE-2026-3805","UBUNTU-CVE-2026-3805"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"curl library","requires_auth":"none","summary":"A use-after-free flaw in curl's SMB connection reuse allows attackers to potentially execute arbitrary code or cause a denial of service.","user_interaction":"not_required","vuln_class":"use_after_free"},"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-416","name":"Use After Free"}],"description":"When doing a second SMB request to the same host again, curl would wrongly use\na data pointer pointing into already freed memory.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-04-12","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-04-12T11:12:16Z","kind":"github_poc","ref":"https://github.com/Rat5ak/CVE-2026-3805-curl-SMB-UAF","stars":0,"title":"CVE-2026-3805: Use-After-Free in curl SMB connection reuse - heap info disclosure"}],"tier":"weaponised"},"has_fix":true,"headline":"use after free in SMB connection reuse","id":"CVE-2026-3805","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"haxx:curl","products":["haxx:curl"],"type":"use_after_free","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"SourceCodester/janobe Resort Reservation System room_rates.php sql injection","id":"CVE-2026-3806"},"packages":[],"prev":{"headline":"Tenda i3 WifiMacFilterSet formWifiMacFilterSet stack-based overflow","id":"CVE-2026-3804"},"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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"yes","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-15","vendors":["curl"]},"summary":"A use-after-free flaw in curl's SMB connection reuse allows attackers to potentially execute arbitrary code or cause a denial of service.","url":"https://insights.sbomify.com/CVE-2026-3805/"}
