Official description

Flyte 2.0.1 through 2.0.51 contains a cleartext secret storage vulnerability that allows users with Pod read access to obtain secrets by reading init container environment variables. The embedded secret manager webhook writes base64-encoded FILE-mounted secret values into the SECRETS environment variable, letting principals without Secret store access decode them from the Pod spec.
