Wallos is an open-source, self-hostable personal subscription tracker.

MEDIUM 4.3EPSS 0.19%

Does this matter?

Lower severity and a low EPSS score (0.19%). Track it; it rarely justifies an emergency change on its own.

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.
