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-2026-86410/ (Markdown: https://insights.sbomify.com/CVE-2026-86410/index.md)","id":"CVE-2026-86410","markdown":"https://insights.sbomify.com/CVE-2026-86410/index.md","name":"CVE-2026-86410","record":{"aliases":["ALPINE-CVE-2026-86410","AZL-109962","AZL-110169","AZL-110232","AZL-110295","BELL-CVE-2026-86410","CURL-CVE-2026-86410","DEBIAN-CVE-2026-86410","ECHO-5141-9c8a-21a9","GHSA-4fmg-fm23-j6fc","MINI-3f82-2g27-whfr","UBUNTU-CVE-2026-86410"],"analysis":null,"analysis_generated_by":null,"assigner":"curl","cpe":[],"cvss":{"score":8.1,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-297","name":"Improper Validation of Certificate with Host Mismatch"}],"description":"A flaw in the curl command line tool's logic makes it only set SSH host\nverification options when interacting directly using SFTP or SCP, and not as a\nresult of following a redirect.","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":"redirect to SFTP or SCP bypasses host verification","id":"CVE-2026-86410","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":null,"year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"FTP connection reuse inherits client-certificate","id":"CVE-2026-86411"},"packages":[],"prev":{"headline":"stale SigV4 headers sent unintended","id":"CVE-2026-86409"},"products":["curl"],"published":"2026-10-20","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-10-29","vendors":["curl"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2026-86410/"}
