{"schema":"threatline.record/2","record":{"id":"CVE-2026-61843","aliases":["GHSA-r787-5hp3-4874"],"summary":"FileRise: Unauthenticated File Overwrite Through Upload-Enabled Folder Shares","details":"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.","categories":["Unclassified"],"product":"FileRise","vendor":"error311","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-61843","source_modified_at":"2026-10-15T15:05:44.030Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"FileRise","vendor":"error311","versions":[{"status":"affected","version":"< 3.18.0"}],"defaultStatus":null},{"source":"GitHub Advisory Database","source_url":"https://github.com/error311/FileRise/security/advisories/GHSA-r787-5hp3-4874","source_modified_at":"2026-07-14T03:02:17Z","fetched_at":"2026-10-24T00:31:04.721601Z","package":{"ecosystem":"","name":"FileRise"},"range":"v3.17.0"}],"fixed_versions":[],"cvss":8.2,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00307,"percentile":0.22288,"score_date":"2026-10-23"},"published_at":"2026-10-14T20:22:57.741Z","modified_at":"2026-10-15T15:05:44.030Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-61843","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-15T15:05:44.030Z"},{"source":"GitHub Advisory Database","url":"https://github.com/error311/FileRise/security/advisories/GHSA-r787-5hp3-4874","fetched_at":"2026-10-24T00:31:04.721601Z","source_modified_at":"2026-07-14T03:02:17Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-61843","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","GitHub Advisory Database","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/error311/FileRise/security/advisories/GHSA-r787-5hp3-4874","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":"yes","technical_impact":"partial","assessed_at":"2026-10-15T15:05:37.325468Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-15T15:05:44.030Z","content_hash":"96bbc093e410869cb4131b071814ab13b2b19c98162ef29fb42188bdc539deed"}}
