HIGHCVSS 7.5/10EPSS 3.41%

Last modified

CVE-2020-1942 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. In Apache NiFi 0.0.1 to 1.11.0, the flow fingerprint factory generated flow fingerprints which included sensitive property descriptor values. In the event a node attempted to join a cluster and the cluster flow was not inheritable, the flow fingerprint of both the cluster and local flow was printed, potentially containing sensitive values in plaintext.. EPSS estimates a 3.41% chance of exploitation in the next 30 days.
