{"cve":"CVE-2026-105630","nvd":{"published":"2026-10-05T18:17:36.250","modified":"2026-10-05T19:17:17.093","status":"Deferred","description":"Plane is an open-source project management tool. Prior to 1.4.0, an authenticated low-privilege workspace member, including a Guest, can upload an image/svg+xml file as a generic or issue attachment. The file retains the attacker-controlled Content-Type, and the asset-download endpoint creates a presigned URL with Content-Disposition: inline. In the default self-hosted MinIO deployment, the asset URL is served from the same origin as the Plane application, allowing embedded SVG JavaScript to execute in the application's security context. A victim, including a workspace administrator, who opens the link can have the session compromised through stored XSS, leading to account takeover. 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:R/S:C/C:H/I:H/A:N","score":8.7},"cwes":["CWE-79","CWE-434","CWE-616"],"references":["https://github.com/makeplane/plane/commit/9dff20e04808286acb372119d88c666b802b1d50","https://github.com/makeplane/plane/pull/9312","https://github.com/makeplane/plane/releases/tag/v1.4.0","https://github.com/makeplane/plane/security/advisories/GHSA-ch8j-vr4r-qf6h","https://github.com/makeplane/plane/security/advisories/GHSA-ch8j-vr4r-qf6h"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:57:46.668721662+00:00"},"epss":{"cve":"CVE-2026-105630","score":0.00214,"percentile":0.11622,"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).
