It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-79779 in the wild and no public exploit code.\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-2026-79779/ (Markdown: https://insights.sbomify.com/CVE-2026-79779/index.md)","id":"CVE-2026-79779","markdown":"https://insights.sbomify.com/CVE-2026-79779/index.md","name":"CVE-2026-79779","record":{"aliases":["BIT-rclone-2026-79779","DEBIAN-CVE-2026-79779","GHSA-9mph-vxjp-r3rx","GHSA-h4mf-4v27-hggj","GO-2026-6197","MINI-33wg-rg8j-jc2g","MINI-497w-rpcc-vpvh","MINI-5fx4-pg4r-qvgw","MINI-67vg-59gc-4p2r","MINI-7h35-gj84-5wpw","MINI-cw3r-6c77-wg86","MINI-j592-mcwx-mw7r","MINI-x6w4-52gc-7mf8","UBUNTU-CVE-2026-79779"],"analysis":{"component_type":"developer_tool","fix_type":"upgrade","impacts":["data_read","account_takeover"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"rclone file sync tool","requires_auth":"none","summary":"An on-path attacker can capture credentials via HTTPS-to-HTTP redirects in rclone, enabling unauthorized WebDAV access and data theft.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":6,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:A/AC:H/AT:P/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-319","name":"Cleartext Transmission of Sensitive Information"}],"description":"rclone versions before v1.75.0 fail to reject transport downgrades in redirect handling, allowing Basic authorization and Cookie headers to be replayed over plaintext HTTP after same-host HTTPS-to-HTTP redirects.
