An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-32749 exists.\n\nAffected packages and fixed versions:\n- github.com/siyuan-note/siyuan/kernel (Go): affected all versions; no fix listed\n- github.com/siyuan-note/siyuan/kernel (Go): affected all versions up to 0.0.0-20260313024916-fd6526133bb3; no fix listed\n- github.com/siyuan-note/siyuan/kernel (Go): affected all versions up to 0.0.0-20260313024916-fd6526133bb3; 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-2026-32749/ (Markdown: https://insights.sbomify.com/CVE-2026-32749/index.md)","id":"CVE-2026-32749","markdown":"https://insights.sbomify.com/CVE-2026-32749/index.md","name":"CVE-2026-32749","record":{"aliases":["GHSA-qvvf-q994-x79v","GO-2026-4707"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"SiYuan knowledge management","requires_auth":"high_privilege","summary":"An admin can exploit path traversal in SiYuan import APIs to write arbitrary files, potentially achieving remote code execution or data destruction.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"siyuan","vendor":"b3log"}],"cvss":{"score":7.6,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:L/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-73","name":"External Control of File Name or Path"},{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"SiYuan is a personal knowledge management system.
