CVE-2026-73405

An authorization bypass vulnerability in Vulnerability-Lookup allowed inactive or unconfirmed accounts to subscribe to Server-Sent Events (SSE) streams through the /pubsub/subscribe/<topic> endpoint. The token_required decorator used by the Pub/Sub interface authenticated requests solely by matching the X-API-KEY header against an existing user API key. Unlike the REST API authentication mechanism, it did not verify the account's is_active and is_confirmed state. Because the self-registration process issues an API key before account confirmation is completed, an attacker could create an account and immediately use the resulting API key to access Pub/Sub topics that should only be available to active, confirmed users. This could expose stream events that would otherwise be inaccessible through the REST API, including newly submitted or not-yet-moderated data such as comments. The vulnerability results from inconsistent authorization enforcement between the REST API and the SSE streaming interface. The patch corrects the issue by requiring accounts to be both active and confirmed before permitting access to Pub/Sub streams, bringing the SSE authorization boundary in line with the REST API.
