CVE-2024-51408Public exploitNetwork attack vector

AWS credential disclosure via noncanonical metadata address

Published Nov 4, 2024 · Updated Nov 5, 2024

SSRF in Appsmith Community 1.8.3 through 1.45 allows remote authenticated users to read AWS metadata through a REST datasource. WebClientUtils compared a datasource host with blocked literal strings without first canonicalizing alternate IPv6 forms, so equivalent forms reached the metadata service. An account able to create and run an API datasource is required, and an AWS-hosted instance with reachable metadata can disclose instance credentials.
