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-2026-86415/ (Markdown: https://insights.sbomify.com/CVE-2026-86415/index.md)","id":"CVE-2026-86415","markdown":"https://insights.sbomify.com/CVE-2026-86415/index.md","name":"CVE-2026-86415","record":{"aliases":["ALPINE-CVE-2026-86415","CURL-CVE-2026-86415","DEBIAN-CVE-2026-86415","GHSA-4g5c-8qrq-wcmw","MINI-j9v5-c8vg-xrc9"],"analysis":null,"analysis_generated_by":null,"assigner":"curl","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"libcurl's connection cache match function never considers the automatic client\ncertificate option, so a cached, already authenticated Schannel connection can\nbe handed to a transfer that got redirected to a different origin, even though\nthe code explicitly switched off the auto client cert option for that transfer\nto prevent exactly this.","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":"auto client cert connection reuse mixup","id":"CVE-2026-86415","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":null,"year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"ILIAS before 9.23, 10.11, and 11.4 Missing Authorization in Group Object Action Methods","id":"CVE-2026-86416"},"packages":[],"prev":{"headline":"leaking host credentials to HTTP proxy","id":"CVE-2026-86414"},"products":["curl"],"published":"2026-10-20","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-10-20","vendors":["curl"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2026-86415/"}
