CVE-2026-76080
Probo: Unauthenticated cross-tenant and hidden-item disclosure via Query.node in the public Trust Center API
Probo is a self-hostable governance, risk, and compliance (GRC) platform built for engineering and security teams. Prior to version 0.224.0, the public Trust Center GraphQL API exposes Query.node(id:) with @authentication(required: OPTIONAL) — an unauthenticated internet visitor to any published trust center can call it. Six of its type branches — Organization, Framework, Audit, ThirdParty (subprocessor), TrustCenter, and TrustCenterReference — resolve the object with a tenant scope derived from the client-supplied GID itself (coredata.NewScopeFromObjectID(id)) and load it with a bare Get(scope, id) that performs no comparison to the current trust center's OrganizationID and no showOnTrustCenter/visibility check. (The Document and File branches, by contrast, correctly pass trustCenter.OrganizationID and check visibility). This issue has been patched in version 0.224.0.

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.
