It builds the plugin install path from an unsanitized name in server/routerTrpc/plugin.ts, and the plugin.installPlugin tRPC procedure is open to any authenticated user. Thus, a name containing ../ sequences writes the downloaded plugin files outside the plugins directory. Because the official Docker image runs as root, an authenticated attacker overwrites a root-owned startup file and achieves remote code execution as root. Self-registration for an account may be possible.","categories":["Unclassified"],"product":"Blinko","vendor":"Blinko","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-108980","source_modified_at":"2026-10-13T19:12:39.874Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Blinko","vendor":"Blinko","versions":[{"lessThanOrEqual":"1.8.8","status":"affected","version":"0","versionType":"semver"}],"defaultStatus":"unknown"}],"fixed_versions":[],"cvss":8.8,"severity":"High","kev":{"listed":false},"epss":{"probability":0.01063,"percentile":0.64375,"score_date":"2026-10-23"},"published_at":"2026-10-12T01:55:59.223Z","modified_at":"2026-10-13T19:12:39.874Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-108980","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-13T19:12:39.874Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-108980","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/kashishtopi/blinko-plugin-path-traversal-rce","tags":["exploit","technical-description"]},{"source":"CVE List","url":"https://github.com/blinkospace/blinko/blob/178e4b3538a21823a50ac2481e653d56cb1ffa86/server/routerTrpc/plugin.ts#L273","tags":["product"]},{"source":"CVE List","url":"https://github.com/blinkospace/blinko/blob/178e4b3538a21823a50ac2481e653d56cb1ffa86/app/src/pages/signin.tsx#L238-L243","tags":["product"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"no","technical_impact":"total","assessed_at":"2026-10-13T19:12:25.927139Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-13T19:12:39.874Z","content_hash":"33478edbdb112ef8cabbb69523b67a14f1591dcfef1758b7b3d20dbbe12d9244"}}
