Technical description

phpUploader before 2.0.2 contains an unauthenticated information disclosure vulnerability that allows remote attackers to access the full contents of the uploaded-files database table by visiting any page of the application. The index model executes an unbounded SELECT query and embeds the complete JSON-encoded result set in an inline script block, exposing uploader IP addresses, Argon2ID key hashes, internal filenames, and SHA-256 fingerprints.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
