9.8 CRITICALPublic exploitEPSS 0.52%
  1. Published5 May 2026

Description

Kestra v1.3.3 and before is vulnerable to SQL Injection. The vulnerability occurs because user-controlled input from a GET parameter is directly concatenated into an SQL query without proper sanitization or parameterization. As a result, attackers can inject arbitrary SQL expressions into the database query.
