{"id":"CVE-2026-61843","published":"2026-10-14T21:17:37.947","lastModified":"2026-10-15T16:18:18.850","description":"FileRise is a self-hosted web-based file manager with multi-file upload, editing, and batch operations. Prior to 3.18.0, FileRise upload-enabled shared-folder and upload-only links do not reject a destination filename that already exists. An unauthenticated visitor with a valid share token and any configured share password can upload a file with the same name as an existing file and silently replace its content while the original uploader metadata remains. The same replacement gap affects ordinary authenticated uploads through /api/upload/upload.php and authenticated upload-only users who lack edit authority over the existing file. This issue is fixed in version 3.18.0.","cvssScore":8.2,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:L","cwes":["CWE-862"],"vendors":[],"products":[],"references":[{"url":"https://github.com/error311/FileRise/commit/9ed1a38f00918849dbda30f54291d1451ed80d11","tags":[]},{"url":"https://github.com/error311/FileRise/releases/tag/v3.18.0","tags":[]},{"url":"https://github.com/error311/FileRise/security/advisories/GHSA-r787-5hp3-4874","tags":[]},{"url":"https://github.com/error311/FileRise/security/advisories/GHSA-r787-5hp3-4874","tags":[]}],"exploitRefs":[{"url":"https://github.com/error311/FileRise/commit/9ed1a38f00918849dbda30f54291d1451ed80d11","tags":[]},{"url":"https://github.com/error311/FileRise/releases/tag/v3.18.0","tags":[]},{"url":"https://github.com/error311/FileRise/security/advisories/GHSA-r787-5hp3-4874","tags":[]},{"url":"https://github.com/error311/FileRise/security/advisories/GHSA-r787-5hp3-4874","tags":[]}],"hasPoc":true,"ai":null}
