An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-49244 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/drakkan/sftpgo/v2 (Go): affected from 2.2.0; fixed in 2.7.3\n- github.com/drakkan/sftpgo/v2 (Go): affected from 2.2.0; fixed in 2.7.3\n- github.com/drakkan/sftpgo/v2 (Go): affected from 2.2.0; fixed in 2.7.3\n- github.com/drakkan/sftpgo (Go): affected all versions; no fix listed\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-2026-49244/ (Markdown: https://insights.sbomify.com/CVE-2026-49244/index.md)","id":"CVE-2026-49244","markdown":"https://insights.sbomify.com/CVE-2026-49244/index.md","name":"CVE-2026-49244","record":{"aliases":["GHSA-h64p-8h4r-6gfh","GO-2026-5902"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"SFTPGo file transfer","requires_auth":"none","summary":"An unauthenticated attacker can bypass path confinement in public browsable shares to read files outside the shared directory via partial ZIP downloads.","user_interaction":"not_required","vuln_class":"path_traversal"},"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:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"SFTPGo is an open source, event-driven file transfer solution. From 2.2.0 until 2.7.3, the public web-client partial ZIP download endpoint for a browsable share validates client-supplied files entries with a raw byte-prefix comparison rather than a directory-boundary-aware check. An unauthenticated requester who can reach a public share can select a canonical path outside the shared directory when the target path begins with the shared directory's name, such as a sibling path that shares the same prefix. The endpoint then includes the out-of-scope file in the generated download, disclosing its contents.
