QuantumNous new-api CVE-2026-9305

No vendor-released patch has been identified at time of analysis, as the vendor did not respond to early disclosure attempts per the CVE description and no fix version is documented in available intelligence sources. Organizations should implement immediate compensating controls: First, restrict network access to the self endpoint containing SearchUserTopUps and SearchAllTopUps functions using firewall rules or reverse proxy ACLs to trusted IP ranges only, understanding this limits legitimate remote access. Second, implement Web Application Firewall (WAF) rules targeting SQL injection patterns in requests to /topup or /self endpoints, with careful tuning to avoid false positives on legitimate search queries. Third, enforce principle of least privilege by reviewing user authentication tokens and restricting low-privilege accounts from accessing topup search functionality if business logic permits, though this may impact user experience. Fourth, enable comprehensive SQL query logging and monitoring to detect exploitation attempts showing UNION, SELECT, OR 1=1, or other SQLi indicators in search parameters. Consider engaging application security consultants to develop and apply a source code patch for model/topup.go implementing parameterized queries or ORM-based database access. Monitor the project repository and VulDB advisories (https://vuldb.com/vuln/365252/cti) for vendor updates, though continued vendor silence suggests evaluating alternative API gateway solutions for long-term risk management.
