New API: SSRF Protection Bypass via Unresolved Hostname in Notification URLs

Collected exploitation and prediction evidence

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

Published

New API is a large language mode (LLM) gateway and artificial intelligence (AI) asset management system. Prior to 0.12.0-alpha.1, the default SSRF protection configuration did not apply IP filtering to hostnames; with ApplyIPFilterForDomain disabled by default, URL validation checked domain allow/block rules but did not resolve a hostname and validate the resolved IP address, allowing authenticated users to configure Webhook, Bark, or Gotify notification URLs that point at an internal or metadata IP address. This issue is fixed in version 0.12.0-alpha.1.

## Summary The default SSRF protection configuration did not apply IP filtering to hostnames. With `ApplyIPFilterForDomain` disabled by default, URL validation checked domain allow/block rules but did not resolve a hostname and validate the resolved IP address. Authenticated users could configure notification URLs for Webhook, Bark, or Gotify notifications and point a hostname at an internal or metadata IP address. ## Impact A regular authenticated user could cause the server to send notification requests to internal HTTP services reachable from the deployment network. Depending on the target environment, this could expose sensitive internal data through timing, errors, or response-dependent behavior. The issue is rated High. ## Affected versions Versions before `v0.12.0-alpha.1` are affected. The previous affected range of `<= v0.11.4-alpha.4` was too narrow because the unsafe default remained present until the `v0.12.0-alpha.1` fix. ## Patches This issue is fixed in `v0.12.0-alpha.1`. The default fetch setting now sets `ApplyIPFilterForDomain: true`, causing hostname destinations to be resolved and checked against the configured IP filtering rules during URL validation. This patch addresses the unresolved-hostname bypass for the affected notification URL paths. It does not mark the separate DNS rebinding advisory as fixed, because connection-time IP enforcement is tracked separately. ## Workarounds If upgrading immediately is not possible, explicitly enable `ApplyIPFilterForDomain`, restrict notification URL domains with an allowlist, disable user-configurable notification URLs where practical, and enforce outbound network filtering at the host or network layer. ## Resources - Fixed by commit `20399d3c8fcb4e3649d53163eb11940fd6763743`. - Relevant code paths: `setting/system_setting/fetch_setting.go`, `common/ssrf_protection.go`, `service/webhook.go`, and `service/user_notify.go`.
