Prior to 1.4.0, DuplicateAssetEndpoint fetches a source FileAsset without limiting it to the caller's workspace, allowing cross-workspace asset duplication. WorkspaceFileAssetEndpoint and the legacy FileAssetEndpoint omit workspace authorization, allowing authenticated users to read, create, modify, or delete assets in workspaces where they are not members. Separately, WorkspaceViewViewSet.retrieve lacks the authorization decorator used by its sibling actions, exposing an unauthorized workspace-view read surface. This issue is fixed in 1.4.0.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:L/A:N","score":8.5},"cwes":["CWE-639","CWE-862"],"references":["https://github.com/makeplane/plane/commit/4577dc3f7a6b5a198602b602a45c6b0abdc7204b","https://github.com/makeplane/plane/commit/ac11c3ef7939e31201fa92a17de106906025590f","https://github.com/makeplane/plane/pull/8885","https://github.com/makeplane/plane/pull/9288","https://github.com/makeplane/plane/releases/tag/v1.4.0"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:57:46.668721662+00:00"},"epss":{"cve":"CVE-2026-104971","score":0.00349,"percentile":0.2822,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
