Description
PictShare before 3.7.1 contains an information disclosure vulnerability that allows unauthenticated attackers to obtain the secret delete_code and uploader metadata by calling the API::info() endpoint which returns the complete raw metadata object without a field whitelist. Attackers can use the publicly visible file hash to retrieve the delete_code via the info API and then invoke the delete API to permanently delete arbitrary files, while also exposing uploader IP, User Agent, remote port, and SHA-1 hash, resulting in loss of content integrity, availability, and uploader privacy.
