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-2026-8932 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-2026-8932/ (Markdown: https://insights.sbomify.com/CVE-2026-8932/index.md)","id":"CVE-2026-8932","markdown":"https://insights.sbomify.com/CVE-2026-8932/index.md","name":"CVE-2026-8932","record":{"aliases":["ALPINE-CVE-2026-8932","AZL-91797","AZL-91827","BELL-CVE-2026-8932","CLSA-2026-1786007050","CLSA-2026-1786034027","CLSA-2026-1786034295","CLSA-2026-1786092535","CLSA-2026-1786446944","CLSA-2026-1786480440","CURL-CVE-2026-8932","DEBIAN-CVE-2026-8932","ECHO-b5e8-7a05-5b42","GHSA-m7xm-hf59-w6rj","JLSEC-2026-1217","MINI-c6v5-68cg-7wfp","MINI-h432-768q-x77g","OESA-2026-3675","OESA-2026-3676","OESA-2026-3677","OESA-2026-3678","OESA-2026-3774","ROOT-OS-ALPINE-315-CVE-2026-8932","ROOT-OS-ALPINE-320-CVE-2026-8932","ROOT-OS-ALPINE-321-CVE-2026-8932","ROOT-OS-ALPINE-322-CVE-2026-8932","ROOT-OS-DEBIAN-11-CVE-2026-8932","ROOT-OS-DEBIAN-12-CVE-2026-8932","ROOT-OS-DEBIAN-13-CVE-2026-8932","UBUNTU-CVE-2026-8932","USN-8670-1","USN-8670-2","USN-8670-3"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"libcurl library","requires_auth":"none","summary":"libcurl may reuse connections despite changed mTLS client certificate settings, potentially bypassing mutual TLS authentication requirements.","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:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-305","name":"Authentication Bypass by Primary Weakness"}],"description":"libcurl would reuse a previously created connection even when some mTLS config\nrelated option had been changed that should have prohibited reuse.\n\nlibcurl keeps previously used connections in a connection pool for subsequent\ntransfers to reuse if one of them matches the setup.
