CVE-2026-23846 | Tugtainer vulnerable to Password Exposure via URL Query Parameter

Exp

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.

8.1 3.1 HIGH
CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N Click to expand
Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:R)
A real person has to do something—click, install, enable—otherwise it doesn’t land.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:N)
Service keeps running; no real outage angle.
