CVE-2026-111899
Description
A flaw was found in KitchenOwl. A Server-Side Request Forgery (SSRF) vulnerability in the recipe import functionality allows an authenticated user to bypass IP address filtering through an unfiltered secondary request. By supplying a crafted webpage that redirects or rebinds to internal, loopback, or cloud metadata endpoints, an attacker can access restricted internal network services and disclose sensitive information.
Statement
This vulnerability is rated as having Moderate impact because exploitation requires authenticated access and only allows unauthorized outbound requests to internal or loopback resources, restricting the potential blast radius primarily to low-level information exposure. KitchenOwl is not packaged, shipped, or maintained in any Red Hat product. As a result, Red Hat enterprise software is not affected by this flaw.
Understanding the Weakness (CWE)
Confidentiality
Technical Impact: Read Application Data
Integrity
Technical Impact: Execute Unauthorized Code or Commands
Access Control
Technical Impact: Bypass Protection Mechanism
By providing URLs to unexpected hosts or ports, attackers can make it appear that the server is sending the request, possibly bypassing access controls such as firewalls that prevent the attackers from accessing the URLs directly. The server can be used as a proxy to conduct port scanning of hosts in internal networks, use other URLs such as that can access documents on the system (using file://), or use other protocols such as gopher:// or tftp://, which may provide greater control over the contents of requests.
