Prior to 3.18.0, FileRise flattens logical folder paths into metadata filenames by replacing separators and spaces with hyphens, so distinct folders such as team/docs and team-docs can share one metadata file. Because uploader metadata is used to authorize read_own and ownership-restricted edits, a low-privileged user who controls one colliding folder, knows the target basename, and already has read_own access to the target folder can alter the metadata used by that folder, make the victim file appear attacker-owned, read it, and modify it when edit-own permission is also available. This issue is fixed in version 3.18.0.","state":0,"publishedAt":"2026-10-14T20:23:53.321+00:00","modifiedAt":"2026-10-15T13:55:51.328+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:H/PR:L/UI:N/S:U/C:H/I:H/A:L","score":7.1,"severity":"HIGH"}],"references":["https://github.com/error311/FileRise/security/advisories/GHSA-qpm8-pgmq-wxmh","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-2026-61844","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-61844","identifiers":["CVE-2026-61844"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
