Talend Data Catalog remote harvesting server before 8.0-20230413 contains a /upgrade endpoint that allows an unauthenticated WAR file to be deployed on the server. (A mitigation is that the remote harvesting server should be behind a firewall that only allows access to the Talend Data Catalog server.)
All versions of Talend Data Catalog before 8.0-20230110 are potentially vulnerable to XML External Entity (XXE) attacks in the /MIMBWebServices/license endpoint of the remote harvesting server.
An issue was discovered in Talend Data Catalog before 7.3-20210930. After setting up SAML/OAuth, authentication is not correctly enforced on the native login page. Any valid user from the SAML/OAuth provider can be used as the username with an arbitrary password, and login will succeed.
