CVE-2026-45008Public exploitNetwork attack vector

Directory deletion via unvalidated client URL traversal

Published May 15, 2026 · Updated May 15, 2026

Path traversal in phpMyFAQ before 4.1.2 allows remote authenticated users with INSTANCE_DELETE permission to delete server directories. Client::deleteClientFolder strips only the https:// prefix from a caller-controlled client URL, concatenates the remainder with clientFolder, and recursively deletes the unresolved path. Exploitation requires a multisite deployment with a non-primary instance and delegated INSTANCE_DELETE access; deletion is limited to directories writable by the PHP process.
