What is CVE-2026-50199?

The Wallos Subscription Tracker is vulnerable due to an authorization flaw in its currency exchange endpoint. Prior to version 4.9.1, the system incorrectly loads the first Fixer/API Layer credential globally instead of associating it with the authenticated user. This misconfiguration allows authenticated users, lacking their own provider key, to invoke exchange-rate refreshes using another user's credential. This oversight has been addressed in the release of version 4.9.1, which ensures user-specific credential usage, thereby bolstering security.

Affected Version(s)

Wallos < 4.9.1
