CVE-2023-36542Known exploitationNetwork attack vector

Authenticated code execution via remote driver references

Published Jul 29, 2023 · Updated Feb 13, 2025

Code injection in Apache NiFi 0.0.2 through 1.22.0 allows remote authenticated users to execute custom code through HTTP resource URLs. Affected Processors and Controller Services retrieve drivers or other resources from attacker-specified HTTP locations without a separate remote-resource permission. The user must already be authorized to configure an affected component, and the retrieved code executes within the NiFi process.
