CVE-2023-26526Network attack vector

Staff-level file deletion via path traversal

Published May 17, 2024 · Updated Apr 28, 2026

Path traversal in Nota-Info Bookly 21.7.1 and earlier allows remote authenticated users with staff access to delete server files. Public advisories do not identify the affected handler or parameter; they state only that attacker-controlled paths reach file-system calls without confinement. Staff-level Bookly access is required, and deletion of WordPress files can interrupt the site or support takeover.
