CVE-2026-112288 Details
Description
Krayin CRM 2.2.5 before 2.2.7 contains a server-side request forgery filter bypass that allows users with webhook permissions to reach internal addresses via DNS rebinding. Attackers can return a public address during WebhookService::isSafeEndpoint() validation and an internal address when Guzzle re-resolves, sending blind requests to internal services and cloud metadata endpoints.
A server-side request forgery (SSRF) filter bypass vulnerability has been identified in Krayin CRM versions 2.2.5 prior to 2.2.7. This vulnerability allows users with webhook permissions to access internal addresses through DNS rebinding. Exploitation involves returning a public address during the webhook safety validation, followed by an internal address when the Guzzle HTTP client re-resolves the request. This enables the sending of blind requests to internal services and cloud metadata endpoints.
Users can update to Krayin CRM version 2.2.7 or later, where this vulnerability has been addressed.
