{"schema":"threatline.record/2","record":{"id":"CVE-2026-102980","aliases":["GHSA-ghcr-frqr-6pqr"],"summary":"Plane: Cross-Project Page Content Disclosure via PageVersionEndpoint Missing Project Scope","details":"Plane is an open-source project management tool. Prior to 1.4.0, PageVersionEndpoint in apps/api/plane/app/views/page/version.py scopes page-version lookups by workspace and page identifiers but not by the project_id from the URL. ProjectPagePermission likewise derives the caller's role from the URL project while resolving the requested page workspace-wide, so a member of one project can use that project's identifier to read description_html for a public page in another project in the same workspace. The affected path is read-only and does not enable cross-project page modification. This issue is fixed in version 1.4.0.","categories":["Unclassified"],"product":"plane","vendor":"makeplane","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-102980","source_modified_at":"2026-10-15T14:14:43.959Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"plane","vendor":"makeplane","versions":[{"status":"affected","version":"< 1.4.0"}],"defaultStatus":null},{"source":"GitHub Advisory Database","source_url":"https://github.com/makeplane/plane/security/advisories/GHSA-ghcr-frqr-6pqr","source_modified_at":"2026-09-30T13:56:57Z","fetched_at":"2026-10-23T18:52:38.922436Z","package":{"ecosystem":"other","name":"makeplane/plane"},"range":"<= 1.3.1"}],"fixed_versions":[{"source":"GitHub Advisory Database","source_url":"https://github.com/makeplane/plane/security/advisories/GHSA-ghcr-frqr-6pqr","source_modified_at":"2026-09-30T13:56:57Z","fetched_at":"2026-10-23T18:52:38.922436Z","package":{"ecosystem":"other","name":"makeplane/plane"},"version":"1.4.0"}],"cvss":6.5,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00304,"percentile":0.22023,"score_date":"2026-10-23"},"published_at":"2026-10-14T19:33:07.916Z","modified_at":"2026-10-15T14:14:43.959Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-102980","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-15T14:14:43.959Z"},{"source":"GitHub Advisory Database","url":"https://github.com/makeplane/plane/security/advisories/GHSA-ghcr-frqr-6pqr","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-30T13:56:57Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-102980","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","GitHub Advisory Database","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/makeplane/plane/security/advisories/GHSA-ghcr-frqr-6pqr","tags":["exploit"]},{"source":"CVE List","url":"https://github.com/makeplane/plane/pull/9380","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/makeplane/plane/commit/cfe951c8af41b0fcf1c792e5ad664d00f77709ce","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/makeplane/plane/releases/tag/v1.4.0","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-15T14:12:43.370527Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-15T14:14:43.959Z","content_hash":"77959377ca1f89c86471aa17a930356226617473c93af4257d4509ed916e9184"}}
