Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-54560 exists.\n\nAffected packages and fixed versions:\n- github.com/cloudreve/Cloudreve/v4 (Go): affected from 4.0.0-20260114075425-bc6845bd742c; fixed in 4.0.0-20260606015557-ed20843dc3df\n- github.com/cloudreve/Cloudreve/v4 (Go): affected from 4.0.0-20260114075425-bc6845bd742c; fixed in 4.0.0-20260606015557-ed20843dc3df\n- github.com/cloudreve/Cloudreve/v4 (Go): affected from 4.0.0-20260114075425-bc6845bd742c; fixed in 4.0.0-20260606015557-ed20843dc3df\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-2026-54560/ (Markdown: https://insights.sbomify.com/CVE-2026-54560/index.md)","id":"CVE-2026-54560","markdown":"https://insights.sbomify.com/CVE-2026-54560/index.md","name":"CVE-2026-54560","record":{"aliases":["GHSA-vgj4-345g-jcf8","GO-2026-6022"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["privilege_escalation","data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Self-hosted file manager","requires_auth":"low_privilege","summary":"Attackers can use low-scope OAuth tokens to access high-privilege APIs due to missing client_id claims, enabling unauthorized data access and modification.","user_interaction":"required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":7.6,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:L","version":"3.1"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"}],"description":"Cloudreve is a self-hosted file management and sharing system.
