{"schema":"threatline.record/2","record":{"id":"CVE-2026-61844","aliases":["GHSA-qpm8-pgmq-wxmh"],"summary":"FileRise: Folder Metadata Filename Collisions Bypass \"read_own\" Isolation","details":"FileRise is a self-hosted web-based file manager with multi-file upload, editing, and batch operations. 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.","categories":["Unclassified"],"product":"FileRise","vendor":"error311","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-61844","source_modified_at":"2026-10-15T13:55:51.328Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"FileRise","vendor":"error311","versions":[{"version":"< 3.18.0","status":"affected"}],"defaultStatus":null}],"fixed_versions":[],"cvss":7.1,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00252,"percentile":0.15815,"score_date":"2026-10-23"},"published_at":"2026-10-14T20:23:53.321Z","modified_at":"2026-10-15T13:55:51.328Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-61844","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-15T13:55:51.328Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-61844","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/error311/FileRise/security/advisories/GHSA-qpm8-pgmq-wxmh","tags":["exploit"]},{"source":"CVE List","url":"https://github.com/error311/FileRise/commit/9ed1a38f00918849dbda30f54291d1451ed80d11","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/error311/FileRise/releases/tag/v3.18.0","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"no","technical_impact":"total","assessed_at":"2026-10-15T13:55:23.284160Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-15T13:55:51.328Z","content_hash":"b15c2c1a3c331538c72ec48f98a2b2809374b08f92982913ba92a3d5e601a402"}}
