Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-101051 exists.\n\nAffected packages and fixed versions:\n- github.com/cloudreve/Cloudreve/v4 (Go): affected all versions; no fix listed\n- github.com/cloudreve/Cloudreve/v4 (Go): affected all versions up to 4.0.0-20260606032813-26b6b1044b02; no fix listed\n- github.com/cloudreve/Cloudreve/v4 (Go): affected all versions up to 4.0.0-20260606032813-26b6b1044b02; no fix listed\n- github.com/cloudreve/Cloudreve (Go): affected all versions; no fix listed\n- github.com/cloudreve/Cloudreve/v3 (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-2026-101051/ (Markdown: https://insights.sbomify.com/CVE-2026-101051/index.md)","id":"CVE-2026-101051","markdown":"https://insights.sbomify.com/CVE-2026-101051/index.md","name":"CVE-2026-101051","record":{"aliases":["GHSA-w8j7-39hp-8x59","GHSA-wv98-qffc-cvmj","GO-2026-6289"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Cloud file management","requires_auth":"low_privilege","summary":"Authenticated attackers can exploit path traversal in remote downloaders to write files outside the intended directory in Cloudreve.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":2.3,"severity":"low","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"Cloudreve before 4.16.1 fails to properly sanitize file paths returned by remote downloaders, allowing authenticated users to create files outside the selected destination directory.
