CVE-2026-55459 Details
Description
The Goobi viewer is a web application that allows digitised material to be displayed in a web browser. From version 25.01 to before version 26.05, AuthenticationEndpoint.verifyOpenIdToken builds its verifier as JWT.require(algorithm).withIssuer(issuer).build() and does not enforce the aud claim during cryptographic validation. The aud check is performed manually afterwards via a single string-equality call, which only handles single-string aud values. In a multi-RP IdP setup, a token whose single-string aud matches the viewer's client ID but was issued for a different relying party passes the check and authenticates the attacker as the token's sub. This issue has been patched in version 26.05.
A vulnerability exists in Goobi Viewer versions 25.01 prior to 26.05, where the OpenID token verification process does not properly enforce the audience ('aud') claim during cryptographic validation. The 'aud' check is only performed manually afterwards, using a single string-equality comparison that fails to accommodate multi-relying party (RP) Identity Providers (IdPs). This flaw allows a token with a matching 'aud' value, but issued for a different relying party, to be accepted, potentially authenticating an attacker as the token's subject.
Users can upgrade to Goobi Viewer version 26.05 or later to address this vulnerability.
