CVE-2025-66524 is a critical deserialization vulnerability affecting Apache NiFi versions 1.20.0 through 2.6.0, specifically within the GetAsanaObject Processor. This flaw allows for arbitrary code execution due to unfiltered Java object deserialization when storing and retrieving state information from a configured cache server. With a CVSS score of 8.8 (High), successful exploitation requires an attacker to have direct access to the cache server used by the GetAsanaObject Processor, potentially leading to full compromise of the NiFi system. There is currently no evidence of active exploitation, public exploit code, or significant community discussion regarding this vulnerability.
