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.
Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
