CVE-2026-26957 | Libredesk has an SSRF Vulnerability via Webhooks

Rejected reason: ** REJECT ** DO NOT USE THIS CANDIDATE NUMBER. ConsultIDs: none. Reason: Upon further research, the maintainer determined that the behavior described by the CVE record is intended behavior. Per the GitHub Security Advisory: "Libredesk is a single-tenant, self-hosted application. Configuring outbound webhook URLs requires an admin-only permission that is not granted by default - the operator must explicitly assign it. Anyone holding this permission already has full administrative control over the application, and outbound HTTP to operator-chosen URLs is the documented purpose of the webhook feature. This is working as designed." Notes: none.
