Vulnerability Title
Apache Linkis gateway module token authentication bypass
Source: CVE Program / CVE List V5
Vulnerability Description
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
