Detailsinfo

A vulnerability classified as critical was found in nezhahq nezha up to 2.0.9. This vulnerability affects an unknown function of the component Dashboard. The manipulation with an unknown input leads to a server-side request forgery vulnerability. The CWE definition for the vulnerability is CWE-918. The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

Nezha Monitoring is a self-hostable, lightweight, servers and websites monitoring and O&M tool. From version 0.20.0 to before version 2.0.10, an authenticated Nezha dashboard user can create or update a DDNS profile with provider webhook and configure an arbitrary webhook_url, HTTP method, request body, and headers. When DDNS is triggered for a server that uses that profile, the dashboard process sends the configured request with utils.HttpClient without the SSRF protections used by notification webhooks. This allows a low-privileged authenticated user who controls an owned server/DDNS profile to make the dashboard host issue HTTP requests to loopback or internal network services. The response body is not returned to the attacker in the confirmed path, so this is a blind SSRF / internal state-changing request primitive. This issue has been patched in version 2.0.10.

The advisory is shared for download at github.com. This vulnerability was named CVE-2026-47268 since 05/19/2026. The exploitation appears to be easy. The attack can be initiated remotely. There are neither technical details nor an exploit publicly available.

Upgrading to version 2.0.10 eliminates this vulnerability.
