Attack profile from CVSS 3.1 · CISA ADP. Fix status from CNA and GitHub. Impact type from CWE-326 and CWE-294.
Summary
In Apache Linkis <=1.3.1, due to the default token generated by Linkis Gateway deployment being too simple, it is easy for attackers to obtain the default token for the attack. Generation rules should add random values. We recommend users upgrade the version of Linkis to version 1.3.2 And modify the default token value. You can refer to Token authorization[1] https://linkis.apache.org/docs/latest/auth/token https://linkis.apache.org/docs/latest/auth/token
