{"id":"CVE-2026-104960","published":"2026-10-05T17:17:11.307","lastModified":"2026-10-05T18:17:31.780","description":"Plane is an open-source project management tool. Prior to 1.4.0, Plane exposes the workspace-scoped GET /api/assets/v2/workspaces/{workspace_slug}/download/{asset_id}/ endpoint for project-bound FileAsset objects without enforcing access to the asset's owning project. An authenticated user who belongs to the same workspace, is not a member of the victim's secret project, and knows the target asset UUID can receive a 302 redirect to a signed download URL. The intended project-scoped route for the same asset correctly returns 403. Confirmed affected project-bound asset types are ISSUE_ATTACHMENT, COMMENT_DESCRIPTION, PAGE_DESCRIPTION, and PROJECT_COVER. This bypass exposes private file content protected by the secret project boundary. This issue is fixed in 1.4.0.","cvssScore":6.5,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","cwes":["CWE-639","CWE-862"],"vendors":[],"products":[],"references":[{"url":"https://github.com/makeplane/plane/commit/e63f0c3b3404d669ae05dd9050aab72292f87e5c","tags":[]},{"url":"https://github.com/makeplane/plane/pull/9372","tags":[]},{"url":"https://github.com/makeplane/plane/releases/tag/v1.4.0","tags":[]},{"url":"https://github.com/makeplane/plane/security/advisories/GHSA-wrrw-wvfv-67h7","tags":[]},{"url":"https://github.com/makeplane/plane/security/advisories/GHSA-wrrw-wvfv-67h7","tags":[]}],"exploitRefs":[{"url":"https://github.com/makeplane/plane/commit/e63f0c3b3404d669ae05dd9050aab72292f87e5c","tags":[]},{"url":"https://github.com/makeplane/plane/pull/9372","tags":[]},{"url":"https://github.com/makeplane/plane/releases/tag/v1.4.0","tags":[]},{"url":"https://github.com/makeplane/plane/security/advisories/GHSA-wrrw-wvfv-67h7","tags":[]},{"url":"https://github.com/makeplane/plane/security/advisories/GHSA-wrrw-wvfv-67h7","tags":[]}],"hasPoc":true,"ai":null}
