Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-56768 in the wild and no public exploit code.\n\nAffected product: haiwen seahub. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-56768/ (Markdown: https://insights.sbomify.com/CVE-2026-56768/index.md)","id":"CVE-2026-56768","markdown":"https://insights.sbomify.com/CVE-2026-56768/index.md","name":"CVE-2026-56768","record":{"aliases":["GHSA-w52g-25r7-3c46"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Seahub file sharing","requires_auth":"low_privilege","summary":"Unauthenticated attackers with a share-link token can bypass authentication to download entire shared directory trees via the share-link-zip-task endpoint.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"Seahub before 13.0.23 does not enforce SHARE_LINK_LOGIN_REQUIRED on GET /api/v2.1/share-link-zip-task/, allowing unauthenticated users to bypass authentication.
