{"id":"CVE-2026-108980","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-108980","generatedAt":"2026-10-28T02:58:56.116Z","title":"Blinko through 1.8.8 allows directory traversal, overwriting startup files as root, via installPlugin.","description":"Blinko through 1.8.8 allows directory traversal, overwriting startup files as root, via installPlugin. 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.","published":"2026-10-12T02:16:57.000Z","lastModified":"2026-10-16T19:56:16.000Z","status":"Deferred","sourceIdentifier":"cve@mitre.org","cvss":{"version":"3.1","score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-24"],"affected":[],"epss":{"score":0.01063,"percentile":0.64411,"date":"2026-10-26","history":[{"date":"2026-10-12","score":0.01063,"percentile":0.63708}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (1.06%).
