Code execution via attacker-selected local JAR loading
Published Oct 14, 2025 · Updated Oct 14, 2025
Improper input validation in Provectus Kafka UI 0.6.0 through 0.7.2 allows remote attackers to execute code through custom Serde configuration. CustomSerdeLoader accepts a filePath and className, creates a child-first loader for a readable local JAR, then instantiates and configures the selected class without restricting its origin. Exploitation requires dynamic configuration access and an attacker-controlled JAR already present on the Kafka UI host; the published evidence does not establish code upload through the API.
