That value is stored and later used directly by the subscription delivery worker as the destination of a server-side HTTP POST request.\n\nThe codebase already contains an outbound SSRF guard, `assert_safe_url()`, which blocks loopback, private, link-local, and metadata-style destinations. However, the subscription webhook delivery path does not appear to apply this guard either when the subscription is created or immediately before delivery.\n\nAs a result, an authenticated user can configure a webhook destination such as `http://127.0.0.1:9999/ssrf`, trigger a matching fact-change event, and cause the Stigmem server to issue a server-side HTTP request to an internal loopback address.\n\n### Details\n\nRelevant files:\n\n```text\nnode/src/stigmem_node/routes/subscriptions.py\nnode/src/stigmem_node/subscription_delivery.py\nnode/src/stigmem_node/models/subscriptions.py\nnode/src/stigmem_node/utility/net_util.py\n\nSubscriptionCreateRequest accepts delivery_address as a plain string and validates only that it has a minimum length:\n\nclass SubscriptionCreateRequest(BaseModel):","public_affected_ranges":["< 0.9.0a11"]}],"null_published_at":"2026-11-03T10:03:26.558Z","source_updated_at":"2026-08-20T18:30:52.000Z","source_disclosed_at":"2026-08-20T18:30:50.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-11-02T20:14:33.912Z"}],"next_cursor":null,"snapshot_revision":"42594"}
