CVE-2026-55463 Details
Description
The Goobi viewer is a web application that allows digitised material to be displayed in a web browser. From version 4.11.0 to before version 26.05, several Jakarta WebSocket endpoints in goobi-viewer-core (DownloadTaskEndpoint, CampaignEndpoint, AutocompleteEndpoint, UserEndpoint) accept connections without verifying that the associated HttpSession belongs to a logged-in user, and none validate the Origin header against an allowlist. An unauthenticated attacker can therefore connect to these endpoints; through CampaignEndpoint this allows polluting the in-process crowdsourcing page-lock map and broadcasting forged lock messages, disrupting reviewers' work. This issue has been patched in version 26.05.
A vulnerability exists in Goobi Viewer WebSocket endpoints, specifically in the 'goobi-viewer-core' component, versions 4.11.0 prior to 26.05. These endpoints do not properly authenticate users or validate the 'Origin' header, allowing unauthenticated attackers to disrupt crowdsourcing activities by sending false lock messages. This issue has been addressed in version 26.05.
Users can upgrade to Goobi Viewer version 26.05 to address this vulnerability.
