Executive Summary
A roundup of OWASP and Check Point reporting says longer indirect prompt-injection payloads rose sharply in 2026, as did high-risk prompts that could trigger data leakage in enterprise AI traffic.
What Happened
This roundup summarizes recent OWASP and Check Point reporting on prompt injection, data leakage, and AI supply-chain risk. It says detections of longer indirect prompt-injection payloads increased sharply in 2026 and that high-risk prompts capable of triggering data leakage also rose in enterprise AI traffic.
Vulnerability / Attack Technique
