Overview

CVE-2026-23846 is a high-severity vulnerability. It was published on January 19, 2026 and has a CVSS 3.1 base score of 8.1 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.1, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

Tugtainer is a self-hosted app for automating updates of Docker containers. In versions prior to 1.16.1, the password authentication mechanism transmits passwords via URL query parameters instead of the HTTP request body. This causes passwords to be logged in server access logs and potentially exposed through browser history, Referer headers, and proxy logs. Version 1.16.1 patches the issue.

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.
