CVE-2026-61518
HighCVSS 8.8Summary
ISPConfig contains an authenticated SQL injection vulnerability in the Remote API. The primary_id parameter in delete and update methods is concatenated directly into SQL WHERE clauses without integer casting or parameterized binding. A user with any low-privilege function permission can inject arbitrary SQL, delete or modify records across all tenants, and extract data including password hashes.
Risk Assessment
An attacker can gain unauthorized access to all clients' data, compromising confidentiality and integrity of the control panel database.
Recommendation
Apply the vendor-provided patch or restrict access to the Remote API and enforce parameterized queries.
Original NVD description (English source)
ISPConfig contains an authenticated SQL injection vulnerability in the Remote API. The primary_id parameter passed to delete and update API methods is concatenated directly into SQL WHERE clauses without integer casting or parameterized query binding. The built-in SQL injection scanner does not block quote-free boolean payloads and does not reject requests in its default configuration. A remote API user holding any single low-privilege function permission can inject arbitrary SQL to delete or modify records across all tenants in the control panel database and extract arbitrary data via blind boolean inference, including password hashes and client records.
