Unauthenticated SSRF via undisclosed request handling

Published Aug 20, 2025 · Updated Jun 5, 2026

SSRF in PİK Online before 3.1.5 allows remote attackers to make the server issue requests to unintended network destinations. TR-CERT and the vendor have not disclosed the affected endpoint, accepted input, or validation failure that permits attacker-selected destinations. No authentication or user interaction is required; successful requests can expose sensitive data and cause limited data modification or service interruption.
