An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-13034 in the wild and no public exploit code.\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-2025-13034/ (Markdown: https://insights.sbomify.com/CVE-2025-13034/index.md)","id":"CVE-2025-13034","markdown":"https://insights.sbomify.com/CVE-2025-13034/index.md","name":"CVE-2025-13034","record":{"aliases":["ALPINE-CVE-2025-13034","CURL-CVE-2025-13034","DEBIAN-CVE-2025-13034","GHSA-9r76-qj98-jfhc","JLSEC-2026-426","MINI-c73v-v84q-fmgc","UBUNTU-CVE-2025-13034"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"curl library","requires_auth":"none","summary":"Attackers can bypass certificate pinning in curl when using QUIC with GnuTLS and disabled verification, allowing man-in-the-middle attacks.","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":5.9,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-295","name":"Improper Certificate Validation"}],"description":"When using `CURLOPT_PINNEDPUBLICKEY` option with libcurl or `--pinnedpubkey`\nwith the curl tool, curl should check the public key of the server certificate\nto verify the peer.\n\nThis check was skipped in a certain condition that would then make curl allow\nthe connection without performing the proper check, thus not noticing a\npossible impostor.
