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-2026-71310 exists.\n\nAffected packages and fixed versions:\n- github.com/rclone/rclone (Go): affected all versions; fixed in 1.75.0\n- github.com/rclone/rclone (Go): affected all versions; fixed in 1.75.0\n- github.com/rclone/rclone (Go): affected all versions; fixed in 1.75.0\n- rclone (Bitnami): affected all versions; fixed in 1.75.0\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-2026-71310/ (Markdown: https://insights.sbomify.com/CVE-2026-71310/index.md)","id":"CVE-2026-71310","markdown":"https://insights.sbomify.com/CVE-2026-71310/index.md","name":"CVE-2026-71310","record":{"aliases":["BIT-rclone-2026-71310","DEBIAN-CVE-2026-71310","GHSA-xhf4-832v-7xcr","GO-2026-6199","MINI-3r7p-w9cf-wmmc","MINI-464m-jqhj-hjgc","MINI-f6rj-8cmm-5v5c","MINI-g79h-rp7j-xf5v","MINI-jg75-53m6-9795","MINI-qfwf-37fr-q395","MINI-v26j-vhpx-34pf","MINI-vhrv-5xp8-c3cv","UBUNTU-CVE-2026-71310"],"analysis":{"component_type":"developer_tool","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"Cloud storage sync tool","requires_auth":"none","summary":"A malicious proxy can cause rclone to crash by sending oversized HTTP CONNECT response headers, requiring a proxy configuration to exploit.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":5.9,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"},{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"rclone is a command-line program to sync files and directories to and from different cloud storage providers. Prior to 1.75.0, the shared HTTP CONNECT helper in lib/proxy/http.go parses proxy CONNECT responses with http.ReadResponse over an unrestricted buffered reader, allowing a malicious or compromised configured proxy, or an active on-path actor controlling a plaintext HTTP proxy hop, to send oversized headers that grow memory until the rclone process fails. The affected helper is used by FTP and SFTP proxy connections, and SFTP reaches the parser before SSH server authentication, so target host key validation does not constrain a malicious proxy.
