CVE-2026-55486 is a critical cross-site scripting (XSS) vulnerability in the intranda goobi-viewer-core web application. Versions from 25.08 up to but not including 26.05 are affected. The flaw arises because the IIIF Auth 2.0 endpoints auth/login and auth/token accept an origin query parameter without proper validation. This parameter is then embedded unsafely into the Content-Security-Policy header and an HTML response body, enabling reflected XSS attacks. The vulnerability has been patched in version 26.05.

CVE-2026-55465 is a medium severity vulnerability in intranda goobi-viewer-core versions from 22.04 up to but not including 26.05. It involves an unauthenticated REST endpoint that improperly concatenates user input into a Solr query without proper escaping or validation, allowing injection of Solr local-param syntax. This can bypass access-condition filters to access restricted georeferenced records. The issue is fixed in version 26.05.

CVE-2026-55463 is a vulnerability in intranda goobi-viewer-core versions from 4.11.0 up to but not including 26.05. Several Jakarta WebSocket endpoints do not verify that the HttpSession belongs to a logged-in user and do not validate the Origin header. This allows unauthenticated attackers to connect to these endpoints and disrupt the crowdsourcing page-lock mechanism. The issue is fixed in version 26.05.

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.

CVE-2026-55457 is an improper authentication vulnerability in intranda goobi-viewer-core versions prior to 26.05. The issue arises because the application returns an empty string as a default token when no web API token is configured, and the authorization filter accepts requests with an empty token parameter. This allows unauthorized access to endpoints protected by authorization bindings. The vulnerability has been patched in version 26.05.

CVE-2026-55444 is an improper input validation vulnerability in the legacy RSS servlet of intranda goobi-viewer-core prior to version 26.05. The servlet accepts q and filterQuery parameters that are concatenated into Solr queries without proper validation, allowing an unauthenticated attacker to manipulate queries and bypass access restrictions in the generated RSS feed. This issue has been patched in version 26.05.

A path traversal vulnerability (CWE-22) exists in intranda goobi-viewer-core versions 24.03 up to but not including 26.05. The vulnerability occurs because the application improperly handles filenames extracted from a Content-Disposition header, allowing directory traversal sequences or absolute paths to be used. This can lead to arbitrary file writes by the Tomcat process user, potentially resulting in remote code execution. The issue is fixed in version 26.05.

CVE-2026-46651 is a critical vulnerability in intranda goobi-viewer-core versions 24.03 up to but not including 26.05. The DownloadTaskEndpoint WebSocket endpoint (/tasks/download/monitor.socket) accepts download requests from unauthenticated users, allowing unauthorized access to critical functions. This issue has been patched in version 26.05.

CVE-2026-46347 affects the intranda goobi-viewer-core web application prior to version 26.05. The vulnerability involves the generation of password reset links with insufficient randomness, allowing an attacker to potentially brute-force the replacement password if they can approximate the server-side generation time. Exploitation requires the victim to have initiated the password reset and the attacker to infer server time from metadata. This issue has been fixed in version 26.05.

The Goobi viewer is a web application that allows digitised material to be displayed in a web browser. Prior to version 26.05, the password reset token is predictably based on the time of the reset request. An attacker who knows the target's email address can request a reset and then brute-force the token. Exploiting this finding alone forces an unauthorized password reset on any account. This issue has been patched in version 26.05.

CVE-2026-55442 is an improper input validation vulnerability in intranda goobi-viewer-core affecting versions from 23.03 up to but not including 26.05. The flaw involves the SolrTools.cleanUpQuery() function, which attempts to sanitize user-supplied query strings by stripping Solr local-parameter syntax. However, the sanitization can be bypassed by wrapping the local parameter in double curly braces, allowing a valid Solr local parameter to be forwarded. This vulnerability has been patched in version 26.05.

The Goobi viewer is a web application that allows digitised material to be displayed in a web browser. From 4.8.0 to before 26.04.1, the Goobi viewer REST endpoint POST /api/v1/index/stream accepted an arbitrary Solr streaming expression from unauthenticated network clients and forwarded it to the backend Solr server without restriction. An attacker could read the complete Solr index and, in default Solr deployments, also modify or delete indexed records. This vulnerability is fixed in 26.04.1.
