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.","state":0,"publishedAt":"2026-10-14T20:22:57.741+00:00","modifiedAt":"2026-10-15T15:05:44.03+00:00","affected":[{"ecosystem":"Vendor product","name":"FileRise","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"error311\",\n                    \"product\": \"FileRise\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 3.18.0\",\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:N/I:H/A:L","score":8.2,"severity":"HIGH"}],"references":["https://github.com/error311/FileRise/security/advisories/GHSA-r787-5hp3-4874","https://github.com/error311/FileRise/commit/9ed1a38f00918849dbda30f54291d1451ed80d11","https://github.com/error311/FileRise/releases/tag/v3.18.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-61843","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-61843","identifiers":["CVE-2026-61843"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
