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-2026-10536 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-2026-10536/ (Markdown: https://insights.sbomify.com/CVE-2026-10536/index.md)","id":"CVE-2026-10536","markdown":"https://insights.sbomify.com/CVE-2026-10536/index.md","name":"CVE-2026-10536","record":{"aliases":["ALPINE-CVE-2026-10536","AZL-91818","AZL-91839","BELL-CVE-2026-10536","CURL-CVE-2026-10536","DEBIAN-CVE-2026-10536","ECHO-0d6f-7fbe-c7fa","GHSA-wjq8-x4qm-6mmh","JLSEC-2026-1197","MINI-vgm9-vx39-f32r","MINI-x888-fhwf-c2pr","ROOT-OS-ALPINE-315-CVE-2026-10536","ROOT-OS-ALPINE-320-CVE-2026-10536","ROOT-OS-ALPINE-321-CVE-2026-10536","ROOT-OS-ALPINE-322-CVE-2026-10536","ROOT-OS-DEBIAN-12-CVE-2026-10536","ROOT-OS-DEBIAN-13-CVE-2026-10536","UBUNTU-CVE-2026-10536"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"libcurl HTTP library","requires_auth":"none","summary":"A use-after-free in libcurl allows attackers to execute code or cause denial of service when specific HTTP/2 dependency options are used with handle resets.","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":9.8,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"A use-after-free vulnerability exists in libcurl when an application\nconfigures an HTTP/2 stream-dependency tree via `CURLOPT_STREAM_DEPENDS` or\n`CURLOPT_STREAM_DEPENDS_E`, subsequently invokes `curl_easy_reset()`, and\nfinally terminates the handle with `curl_easy_cleanup()`.
