Vulnerability in Apache (CVE-2026-68981)
Summary
Vulnerability in Apache (CVE-2026-68981). Risk of unauthorized operations or information disclosure.
Original description
The description as published by the source.
Apache NiFi 1.5.0 through 2.10.0 support gzip-encoded HTTP requests for the application REST API using a Jersey encoding filter. The framework enforced a configurable maximum request size on the compressed payload rather than the decompressed output, allowing a malicious client to send crafted requests that could consume excessive amounts of memory. Upgrading to Apache NiFi 2.11.0 is the recommended mitigation, which relocates response compression to Jetty Server and disables decompression of gzip-encoded HTTP requests.
