## What is CVE-2026-104051?

CVE-2026-104051 is a high-severity vulnerability in HaschekSolutions pictshare, published on 1 Oct 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official 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.

Weakness: CWE-522 (Insufficiently Protected Credentials)
