CVE-2026-26957
Libredesk has an SSRF Vulnerability via Webhooks
Description
Libredesk is a self-hosted customer support desk application. Versions prior to 1.0.2-0.20260215211005-727213631ce6 fail to validate destination URLs for webhooks, allowing an attacker posing as an authenticated "Application Admin" to force the server to make HTTP requests to arbitrary internal destinations.
