Attackers with database write access can inject a serialized gadget chain into the permissions table columns processed on every authenticated page load to write arbitrary files, such as PHP webshells, to web-accessible paths.","published":"2026-09-10T17:17:06.083","modified":"2026-09-10T17:17:06.083","cvss":{"score":7.2,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://filerun.com/index.php/changelog?v=2026.3.0"},{"type":"WEB","url":"https://vulncheck.com/blog/filerun-delegated-admin-sql-to-object-injection-rce"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/filerun-php-object-injection-via-perms-getperms"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-09-10T17:17:06.083"}}
