CVE-2026-81658
Foreman: cross-tenant disclosure of template revisions via unauthorized audit lookup
A flaw was found in Foreman. The template revision endpoint does not enforce object-level authorization when retrieving an audited template revision. An authenticated, low privileged user with a template-related permission, such as view_ptables, can obtain historical template contents belonging to another organization or location by supplying the corresponding audit ID. This can result in unauthorized disclosure of historical template contents, which may contain sensitive configuration information, credentials, or other secrets. The REST API revision endpoints correctly restrict this lookup.

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.
