Detailsinfo

A vulnerability classified as critical was found in ellite Wallos up to 4.9.5. This vulnerability affects an unknown functionality of the component OIDC Login. The manipulation with an unknown input leads to a improper authentication vulnerability. The CWE definition for the vulnerability is CWE-287. When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

Wallos is an open-source, self-hostable personal subscription tracker. From version 4.0.0 to before version 4.9.6, Wallos's OIDC login links an incoming OIDC identity to an existing local account by matching the email claim alone, without verifying that the IdP marked that email as verified (email_verified). When Wallos is configured against an IdP that lets a user present an arbitrary or unverified email (multi-tenant IdPs, IdPs with open self-registration, or any IdP the attacker partly controls), an attacker with no Wallos account can authenticate with the admin's email and be logged in as the admin — full account takeover, no password needed. This issue has been patched in version 4.9.6.

The advisory is shared for download at github.com. This vulnerability was named CVE-2026-61641 since 07/10/2026. The exploitation appears to be easy. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. There are neither technical details nor an exploit publicly available.
