CVE-2023-41356Network attack vector

Authenticated cross-user file disclosure via altered file ID

Published Nov 3, 2023 · Updated Oct 14, 2024

Authorization bypass in WisdomGarden TronClass 1.62.41849 allows remote authenticated users to read other users' uploaded files. The upload-file handler accepts a file ID from the request URL without confirming that the requested file belongs to the logged-in account. Any ordinary account can change that identifier and retrieve another user's uploaded content, but the advisory reports no write access.
