From version 25.08 to before version 26.05, the IIIF Auth 2.0 endpoints auth/login and auth/token in AuthorizationFlowResource accept an origin query parameter without validation and then (1) embed it into the Content-Security-Policy: frame-ancestors response header and (2) embed it into an HTML response body as a JavaScript single-quoted postMessage argument. Because the attacker controls both the login and token calls that initiate the flow, the unescaped value yields reflected XSS. This issue has been patched in version 26.05.","state":0,"publishedAt":"2026-10-23T14:17:42.732+00:00","modifiedAt":"2026-10-23T14:17:42.732+00:00","affected":[{"ecosystem":"Vendor product","name":"goobi-viewer-core","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"intranda\",\n                    \"product\": \"goobi-viewer-core\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 25.08, < 26.05\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:N","score":9.3,"severity":"CRITICAL"}],"references":["https://github.com/intranda/goobi-viewer-core/security/advisories/GHSA-975w-g9gj-xq48","https://github.com/intranda/goobi-viewer-core/commit/0e488c6b02a28c1d1a747dfe3958ad2bbcff2d0b","https://github.com/intranda/goobi-viewer-core/releases/tag/v26.05"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-55486","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-55486","identifiers":["CVE-2026-55486"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
