CVE-2026-108980

8.8 · HIGH

Blinko through 1.8.8 allows directory traversal, overwriting startup files as root, via installPlugin.

Published Oct 12, 2026CWE-24EPSS 1.06%

Overview

CVE-2026-108980 is a high-severity vulnerability. It was published on October 12, 2026 and has a CVSS 3.1 base score of 8.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.8, rated HIGH. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical 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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
