Description

A vulnerability has been found in Lybbn Django-Vue-Lyadmin up to 3.2.12. The impacted element is an unknown function of the file backend/application/settings.py of the component JWT Signing. The manipulation of the argument SECRET_KEY leads to use of hard-coded cryptographic key . Remote exploitation of the attack is possible. The exploit has been disclosed to the public and may be used. The project maintainer explains: "The issue with this key is described in the documentation. Developers need to manually change their keys before deployment."

Detection & mitigation playbook

Vulnerability

  1. Detect

    Identify every host running the affected component and compare the installed build against the fixed version below — for source-built or distro-packaged software the version string, not a lockfile, is the source of truth (`dpkg -l`, `rpm -q`, or the binary's own `--version`).

  2. Remediation status

    No fixed release is recorded for CVE-2026-105392 yet. Track the upstream advisory, and apply the exposure-reduction steps below in the meantime.

  3. Mitigate without a patch

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
