Vulnerability from variot

A change introduced in Apache Flink 1.11.0 (and released in 1.11.1 and 1.11.2 as well) allows attackers to read any file on the local filesystem of the JobManager through the REST interface of the JobManager process. Access is restricted to files accessible by the JobManager process. All users should upgrade to Flink 1.11.3 or 1.12.0 if their Flink instance(s) are exposed. The issue was fixed in commit b561010b0ee741543c3953306037f00d7a9f0801 from apache/flink:master. Apache Flink Exists in a vulnerability in externally accessible files or directories.Information may be obtained. Apache Flink is an efficient and distributed general data processing platform. Attackers can use this vulnerability to read sensitive files on the server, use hard-coded credentials to use the vulnerability to read and write HMI configuration files and reset the device

      data: "A change introduced in Apache Flink 1.11.0 (and released in 1.11.1 and 1.11.2 as well) allows attackers to read any file on the local filesystem of the JobManager through the REST interface of the JobManager process. Access is restricted to files accessible by the JobManager process. All users should upgrade to Flink 1.11.3 or 1.12.0 if their Flink instance(s) are exposed. The issue was fixed in commit b561010b0ee741543c3953306037f00d7a9f0801 from apache/flink:master. Apache Flink Exists in a vulnerability in externally accessible files or directories.Information may be obtained. Apache Flink is an efficient and distributed general data processing platform. Attackers can use this vulnerability to read sensitive files on the server, use hard-coded credentials to use the vulnerability to read and write HMI configuration files and reset the device",
