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-2026-105637 exists.\n\nAffected product: makeplane plane. 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-2026-105637/ (Markdown: https://insights.sbomify.com/CVE-2026-105637/index.md)","id":"CVE-2026-105637","markdown":"https://insights.sbomify.com/CVE-2026-105637/index.md","name":"CVE-2026-105637","record":{"aliases":["GHSA-r2hw-fff3-pjwp"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Plane project management","requires_auth":"low_privilege","summary":"A workspace guest can hijack assets from other projects by manipulating bulk asset endpoints, allowing unauthorized access and modification of files.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":9.6,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-639","name":"Authorization Bypass Through User-Controlled Key"}],"description":"Plane is an open-source project management tool. Prior to 1.4.0, ProjectBulkAssetEndpoint.post in apps/api/plane/app/views/asset/v2.py retrieves assets using id__in=asset_ids and workspace__slug=slug but does not constrain the query with project_id from the URL. A workspace Guest can provide asset UUIDs from another project in the same workspace and reassign their issue_id, comment_id, page_id, draft_issue_id, or project_id to an entity the attacker controls. Plane then treats the attacker's project as the new owner and provides a presigned download URL for the hijacked file.
