DescriptionCVE.org

The File Uploads Addon for WooCommerce WordPress plugin before 1.7.6 does not verify that the person requesting a customer-uploaded file is the customer who uploaded it, allowing unauthenticated attackers who know or guess a file's name to download other customers' uploaded files.

AnalysisAI

Unauthenticated disclosure of other customers' uploaded files is possible through the File Uploads Addon for WooCommerce WordPress plugin in versions 1.7.2 through 1.7.5, because the plugin serves stored uploads without verifying that the requester is the customer who originally uploaded the file (CWE-639). An attacker who knows or guesses the exact file name of a previously uploaded file can retrieve it over the network with no account and no user interaction, as reflected by CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N (5.9 Medium) - the High attack complexity stems entirely from the file-name discovery prerequisite, so real-world difficulty hinges on whether the plugin generates guessable or sequential names versus long random tokens. …
