Quick assessment

Affected
intranda goobi-viewer-core
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Goobi 查看器是一款 Web 应用程序，用于在浏览器中展示数字化资料。在 26.05 版本之前，若未配置 webapi.authorization.token 参数，Configuration.getWebApiToken 方法会返回空字符串。AuthorizationFilter 在验证时，会直接将请求提供的令牌与该默认空值进行比较，而未先检查已配置的令牌是否非空。因此，任何带有空 ?token= 参数的请求，若指向受 @AuthorizationBinding 保护的端点，均会被接受。该问题已在 26.05

Vulnerability Title
Goobi viewer: Empty webapi.authorization.token default permits unauthenticated authorization bypass
Source: CVE Program / CVE List V5
Vulnerability Description
The Goobi viewer is a web application that allows digitised material to be displayed in a web browser. Prior to version 26.05, Configuration.getWebApiToken returns the empty string when webapi.authorization.token is not configured. AuthorizationFilter compares the supplied token against this default without first checking that the configured token is non-empty. A request to any @AuthorizationBinding-protected endpoint with an empty ?token= value is therefore accepted. This issue has been patched in version 26.05.
