{"id":"CVE-2026-46652","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-46652","generatedAt":"2026-10-28T01:19:39.760Z","title":"The Goobi viewer is a web application that allows digitised material to be displayed in a web browser.","description":"The Goobi viewer is a web application that allows digitised material to be displayed in a web browser. 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.","published":"2026-10-23T15:17:32.000Z","lastModified":"2026-10-23T16:28:32.000Z","status":"Deferred","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"3.1","score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-22","CWE-73"],"affected":[],"epss":{"score":0.00703,"percentile":0.53016,"date":"2026-10-26","history":[{"date":"2026-10-24","score":0.01095,"percentile":0.65308}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.70%).
