Prior to version 1.4.0, a business logic flaw in FileRise\u2019s file\/folder handling allows low-privilege users to perform unauthorized operations (view\/delete\/modify) on files created by other users. The root cause was inferring ownership\/visibility from folder names (e.g., a folder named after a username) and missing server-side authorization\/ownership checks across file operation endpoints. This amounted to an IDOR pattern: an attacker could operate on resources identified only by predictable names. This issue has been patched in version 1.4.0 and further hardened in version 1.5.0. A workaround for this issue involves restricting non-admin users to read-only or disable delete\/rename APIs server-side, avoid creating top-level folders named after other usernames, and adding server-side checks that verify ownership before delete\/rename\/move.<\/p>\n<p>Severity: 8.1 | HIGH<\/p>\n<p>Visit the link for more details, such as CVSS details, affected products, timeline, and more&#8230;\u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"<p>CVE ID : CVE-2025-62509 Published : Oct. 20, 2025, 6:15 p.m. | 26\u00a0minutes ago Description : FileRise is a self-hosted web-based file manager with multi-file upload, editing, and batch operations.
