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-2026-73605 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/siyuan-note/siyuan/kernel (Go): affected all versions; fixed in 0.0.0-20260812083335-251596fc0de2\n- github.com/siyuan-note/siyuan/kernel (Go): affected all versions; fixed in 0.0.0-20260812083335-251596fc0de2\n- github.com/siyuan-note/siyuan/kernel (Go): affected all versions; fixed in 0.0.0-20260812083335-251596fc0de2\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-2026-73605/ (Markdown: https://insights.sbomify.com/CVE-2026-73605/index.md)","id":"CVE-2026-73605","markdown":"https://insights.sbomify.com/CVE-2026-73605/index.md","name":"CVE-2026-73605","record":{"aliases":["GHSA-hf8h-97gm-4x2p","GO-2026-6626"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"SiYuan note-taking app","requires_auth":"none","summary":"Attackers can probe filesystem existence via path traversal in SiYuan, enabling reconnaissance of host files and directories.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:L/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"SiYuan versions before v3.7.4 contain a path traversal vulnerability in the getUniqueFilename endpoint that allows anonymous readers to probe filesystem existence without validation or confinement.
