CVE-2026-104051
PictShare < 3.7.1 Sensitive Information Disclosure via info API
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.

For agents and automation
Read public disclosures for free as Markdown or JSON. Compatible browsers also expose native WebMCP tools to search disclosures, read this page, and discover API access.
Use the ontology-linked Cyber API with x402 pay per request, or a Y2 Pro or Elite API key with the intel:cyber scope.
Endpoints and access details
https://api.y2.dev/api/v2/cyber/cveshttps://api.y2.dev/api/v2/cyber/cves/{cveId}
A workspace owner or admin can create a Pro or Elite API key. Send Authorization: Bearer <Y2_API_KEY> from your trusted agent runtime.
For x402, omit Authorization and read the HTTP 402 payment challenge before signing a retry. Public browser tools do not make payments.
