{"identifier":"CVE-2026-102980","cve":{"id":"CVE-2026-102980","description":"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.","published":"2026-10-14T20:17:28.600000+00:00","modified":"2026-10-15T15:17:20.270000+00:00","status":"Deferred","score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","cvss_version":"3.1","affected":[],"weaknesses":["CWE-639"],"references":[{"url":"https://github.com/makeplane/plane/commit/cfe951c8af41b0fcf1c792e5ad664d00f77709ce","source":"security-advisories@github.com"},{"url":"https://github.com/makeplane/plane/pull/9380","source":"security-advisories@github.com"},{"url":"https://github.com/makeplane/plane/releases/tag/v1.4.0","source":"security-advisories@github.com"},{"url":"https://github.com/makeplane/plane/security/advisories/GHSA-ghcr-frqr-6pqr","source":"security-advisories@github.com"},{"url":"https://github.com/makeplane/plane/security/advisories/GHSA-ghcr-frqr-6pqr","source":"134c704f-9b21-4f2e-91b3-4a467353bcc0"}],"kev":null,"kev_checked":true,"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","baseScore":6.5,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"NONE","availabilityImpact":"NONE"},"exploitabilityScore":2.8,"impactScore":3.6}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-10-15T14:12:43.370527Z","id":"CVE-2026-102980","options":[{"exploitation":"poc"},{"automatable":"no"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"configurations":[],"source":"nvd","retrieved_at":"2026-10-28T10:22:28.545664+00:00","exploited":false,"kev_stale":false,"products":[],"priority":{"label":"Assess exposure and vendor guidance","reasons":["No higher-priority signal is available in the current stored evidence."]},"epss":{"probability":0.00386,"percentile":0.32649,"date":"2026-10-29","stale":false},"version_assessment":null},"news":[],"campaigns":[],"domains":[{"domain":"github.com","source_url":"https://github.com/makeplane/plane/commit/cfe951c8af41b0fcf1c792e5ad664d00f77709ce","investigate_url":"https://investigate.aeglixmind.com/#github.com"}],"arsenal_url":"https://arsenal.aeglixmind.com/?cve=CVE-2026-102980","catalog_url":"https://cves.aeglixmind.com/cve/CVE-2026-102980","research_url":"https://investigate.aeglixmind.com/research/cve/CVE-2026-102980","coverage":{"news_candidates_checked":0,"campaign_candidates_checked":0,"bounded":false,"notice":"Exact CVE mentions in stored public excerpts and reviewed campaign content only.
