Technical details
The vulnerability is a directory traversal flaw in the 'remoteurl' parameter affecting WP File Download versions up to 6.3.8. An authenticated attacker with Subscriber-level access exploits an unprotected file.save handler to poison the _wpfd_file_metadata['file'] post-meta value with traversal sequences (e.g., ../../../etc/passwd). The streaming endpoint, hooked on init without authentication requirements, resolves and streams the traversed file path to any caller, including unauthenticated visitors. This allows reading of arbitrary files containing sensitive information such as wp-config.php and database credentials. The vulnerability requires initial authenticated access but can be exploited by unauthenticated users post-poisoning.
