CVE-2026-30924 (opens in a new tab)How to fix?
Upgrade github.com/autobrr/qui/internal/api to version 1.15.0 or higher.
Overview
Affected versions of this package are vulnerable to Permissive Cross-domain Policy with Untrusted Domains via a misconfigured CORS policy that reflects arbitrary origins and allows credentials. An attacker can gain unauthorized access to sensitive data and perform actions on behalf of authenticated users by tricking a victim into visiting a malicious webpage, which then interacts with the application using the victim's browser session. This may result in exposure of credentials, compromise of connected accounts, or even full system takeover depending on deployment.
Note: This is only exploitable if the application is accessed via a domain or IP address other than localhost or 127.0.0.1, and the victim loads a malicious webpage in their browser.
Workaround
This vulnerability can be mitigated by using a unique hostname, not exposing the instance to untrusted networks, avoiding clicking or automatically loading untrusted webpages, running the application in a containerized environment, and signing out after use.
