CVE-2021-42837 is a critical authentication bypass vulnerability affecting Talend Data Catalog versions prior to 7.3-20210930. When SAML/OAuth is configured, the native login page fails to properly enforce authentication, allowing any valid user from the identity provider to log in with an arbitrary password. This flaw carries a CVSS score of 9.8 (Critical) due to its network-based attack vector, low complexity, and potential for complete compromise of confidentiality, integrity, and availability. While no public exploit code (Metasploit, Nuclei, ExploitDB) or active exploitation (KEV list) has been identified, and community discussion is minimal, the high FAUCET Risk Score of 79/100 indicates a significant theoretical risk.
