CVE-2026-50199: CWE-863: Incorrect Authorization in ellite Wallos
Description
Wallos is an open-source, self-hostable personal subscription tracker. Prior to version 4.9.1, endpoints/currency/update_exchange.php loads the first Fixer/API Layer credential globally instead of loading the credential for the authenticated user. As a result, a normal authenticated user without their own provider key can trigger exchange-rate refreshes using another user's stored provider credential. This issue has been patched in version 4.9.1.

Technical Analysis
CVE-2026-50199 describes an incorrect authorization vulnerability (CWE-863) in Wallos before version 4.9.1. The endpoint endpoints/currency/update_exchange.php loads the first Fixer/API Layer credential globally rather than the credential associated with the authenticated user. Consequently, a normal authenticated user lacking their own provider key could invoke exchange-rate refreshes leveraging another user's stored provider credential. This flaw was addressed in Wallos version 4.9.1.
Potential Impact
The vulnerability allows authenticated users without their own API credentials to misuse another user's API key to refresh exchange rates. This results in limited impact, primarily an integrity issue where unauthorized actions can be performed using another user's credentials. There is no confidentiality or availability impact reported.
Mitigation Recommendations
This vulnerability has been patched in Wallos version 4.9.1. Users should upgrade to version 4.9.1 or later to remediate this issue. No other mitigation guidance is provided or necessary.
