CVE-2025-65841 — Acustica-Audio Aquarius security vulnerability

Medium CVSS 6.2

Aquarius Desktop 3.0.069 for macOS stores user authentication credentials in the local file ~/Library/Application Support/Aquarius/aquarius.settings using a weak obfuscation scheme. The password is "encrypted" through predictable byte-substitution that can be trivially reversed, allowing immediate recovery of the plaintext value. Any attacker who can read this settings file can fully compromise the victim's Aquarius account by importing the stolen configuration into their own client or login through the vendor website. This results in complete account takeover, unauthorized access to cloud-synchronized data, and the ability to perform authenticated actions as the user.

Matched remediation archetype

Authorization bypass, IDOR, and cross-tenant access

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Map object and action authorization checks across API, UI, batch, import/export, and background-job paths.
  • Identify tenant, ownership, role, and policy boundaries for affected resources and administrative operations.
  • Use synthetic fixtures to compare intended access matrices without accessing another user's real data.

Remediate safely

  • Enforce server-side authorization at each resource access and state transition using the authenticated principal and trusted tenant context.
  • Scope data queries by tenant and ownership; treat client-supplied identifiers, roles, and policy claims as untrusted.
  • Add deny-by-default policy tests for horizontal and vertical access across every affected transport.
