From version 24.03 to before version 26.05, ExternalFilesDownloader.getFilename() extracts the destination filename from a server-supplied Content-Disposition response header and passes it directly to Path.resolve() without stripping directory components. This allows for a malicious HTTP server that the viewer fetches from to supply an absolute path or ../ traversal sequences as the filename, writing attacker-controlled content to an arbitrary path writable by the Tomcat process. When targeting the deployed web-application directory, this yields remote code execution as the tomcat OS user. This issue has been patched in version 26.05.","state":0,"publishedAt":"2026-10-23T14:15:46.415+00:00","modifiedAt":"2026-10-23T14:15:46.415+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\": \">= 24.03, < 26.05\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8,"severity":"CRITICAL"}],"references":["https://github.com/intranda/goobi-viewer-core/security/advisories/GHSA-r386-2frm-w3v6","https://github.com/intranda/goobi-viewer-core/commit/5281245708447ae3419cb42492fbb8af731a2ce5","https://github.com/intranda/goobi-viewer-core/releases/tag/v26.05"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-46652","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-46652","identifiers":["CVE-2026-46652"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
