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-2025-4947 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-2025-4947/ (Markdown: https://insights.sbomify.com/CVE-2025-4947/index.md)","id":"CVE-2025-4947","markdown":"https://insights.sbomify.com/CVE-2025-4947/index.md","name":"CVE-2025-4947","record":{"aliases":["ALPINE-CVE-2025-4947","AZL-62055","CLEANSTART-2026-FC20847","CURL-CVE-2025-4947","DEBIAN-CVE-2025-4947","ECHO-2ea7-6406-0262","GHSA-ppfq-jg49-mqj4","JLSEC-2026-432","MINI-cqv8-h4hv-gqgj"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"libcurl HTTP client","requires_auth":"none","summary":"libcurl skips certificate verification for QUIC connections to IP addresses, 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":6.5,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-295","name":"Improper Certificate Validation"}],"description":"libcurl accidentally skips the certificate verification for QUIC connections when connecting to a host specified as an IP address in the URL.
