Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-71309 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 from 1.40.0; fixed in 1.75.0\n- github.com/rclone/rclone (Go): affected from 1.40.0; fixed in 1.75.0\n- rclone (Bitnami): affected from 1.40.0; 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-2026-71309/ (Markdown: https://insights.sbomify.com/CVE-2026-71309/index.md)","id":"CVE-2026-71309","markdown":"https://insights.sbomify.com/CVE-2026-71309/index.md","name":"CVE-2026-71309","record":{"aliases":["BIT-rclone-2026-71309","DEBIAN-CVE-2026-71309","GHSA-45pq-889g-fcgh","GO-2026-6184","MINI-3hj9-rc4q-jw39","MINI-49cg-mmww-p4gx","MINI-c4xp-r7g6-jgwf","MINI-c9gc-j54f-85cp","MINI-crg7-ppjm-36gp","MINI-f7cw-x8vc-5x83","MINI-mp9x-crvr-56hf","MINI-w3hj-gv4g-v36x","ROOT-APP-GOBINARY-CVE-2026-71309","UBUNTU-CVE-2026-71309"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":true,"product_category":"rclone REST server","requires_auth":"low_privilege","summary":"An attacker can escape the configured root directory in rclone serve restic to read, modify, or delete files outside the intended scope.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":8.6,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"rclone is a command-line program to sync files and directories to and from different cloud storage providers.
