It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-79783 exists.\n\nAffected packages and fixed versions:\n- github.com/rclone/rclone (Go): affected all versions; fixed in 1.74.4\n- github.com/rclone/rclone (Go): affected all versions; fixed in 1.74.4\n- github.com/rclone/rclone (Go): affected all versions; fixed in 1.74.4\n- rclone (Bitnami): affected all versions; fixed in 1.74.4\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-2026-79783/ (Markdown: https://insights.sbomify.com/CVE-2026-79783/index.md)","id":"CVE-2026-79783","markdown":"https://insights.sbomify.com/CVE-2026-79783/index.md","name":"CVE-2026-79783","record":{"aliases":["BIT-rclone-2026-79783","DEBIAN-CVE-2026-79783","GHSA-945v-v9p3-v5xw","GHSA-vqwj-943v-724g","GO-2026-6190","MINI-5vfw-87j7-9gxw","MINI-8q4f-9c6v-3mfp","MINI-f7pr-grr6-6w3f","MINI-mwq4-gq2v-v75m","MINI-w798-523f-m7r5","MINI-w96w-q4g7-f2w2","UBUNTU-CVE-2026-79783"],"analysis":{"component_type":"developer_tool","fix_type":"upgrade","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"rclone file sync tool","requires_auth":"none","summary":"Attackers can escalate privileges by planting setuid binaries via untrusted remote metadata when rclone preserves file permissions.","user_interaction":"required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":2,"severity":"low","source":"cna","vector":"CVSS:4.0/AV:L/AC:H/AT:P/PR:N/UI:P/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-732","name":"Incorrect Permission Assignment for Critical Resource"}],"description":"rclone before 1.74.4 fails to mask special permission bits when applying source-supplied mode metadata in the local backend, allowing attackers to set setuid/setgid bits on attacker-controlled files.
